Description
Heckler & Koch UMP45, a select-fire submachine gun in .45 ACP. A simple blowback action fires from a closed bolt at about 700 rounds per minute, and the polymer receiver keeps the weight to 2.5 kg. The skeleton stock folds flat along the right side of the receiver, and a Picatinny top rail takes optics over the fixed drum rear sight. Feeds from 25-round polymer magazines.

THIRD-PARTY CONTENT NOTICE
This Mod incorporates third-party 3D models and related material lawfully obtained by
EvilJackk. The primary weapon model was obtained under a Free Standard license that does
not require attribution. Other models used in the Mod were purchased by EvilJackk under
royalty-free licenses. No creator attribution is included because the applicable licenses
do not require it.
EvilJackk does not claim authorship or ownership of the underlying third-party models.
Those models remain governed by the licenses under which they were obtained. Those
licenses are personal or transaction-specific and are not transferred or sublicensed to
any recipient of this Mod. Nothing in this custom license grants permission to extract,
copy, redistribute, relicense, or reuse the third-party models outside the rights, if any,
provided directly by their applicable licenses.
For purposes of this license, third-party models and material are not "Mod Content."
The restrictions in this custom license apply only to EvilJackk's original contributions,
integration work, and other material for which EvilJackk owns or controls the applicable
rights.
This license applies to the official UMP-45 mod published by EvilJackk under the Workshop
ID above (the "Mod"). By downloading, installing, accessing, or using the Mod, you agree
to this license.
1. PLATFORM TERMS AND SCOPE
This is a custom license issued under Section 3 of the Arma Reforger Workshop Terms of
Use. It is subordinate to the Arma Reforger Workshop Terms of Use, the applicable Arma
Reforger EULAs, the Arma Reforger Tools EULA, and Bohemia Interactive's Terms and
Conditions. If this license conflicts with a mandatory provision of those terms, the
mandatory provision controls to the extent of the conflict.
Nothing in this license limits the normal technical functioning of the Arma Reforger
Workshop or any rights granted directly to Bohemia Interactive under its terms.
This license governs only those portions of the Mod for which EvilJackk owns or controls
the applicable rights ("Mod Content"). Bohemia Interactive content and other material
governed by separate terms remain subject to their respective terms.
2. DEFINITIONS
"Dependent Mod" means a separate Arma Reforger Workshop addon that:
- lists the official Mod as a required dependency;
- references or extends the Mod through supported Enfusion mechanisms; and
- does not contain, replace, repackage, or redistribute Mod Content.
"Written Permission" means explicit, scope-specific approval sent by EvilJackk.
Permission may be requested on Discord through @eviljackk. Silence, a pending request,
a casual discussion, or permission from another person does not constitute approval.
Permission applies only to the person, project, and use expressly approved and may not
be transferred or sublicensed.
3. BASIC LICENSE GRANT
Subject to continued compliance with this license, EvilJackk grants you a limited,
non-exclusive, non-transferable, non-sublicensable, and revocable license to:
- download and install the official Mod through the Arma Reforger Workshop;
- use the Mod for non-commercial gameplay within Arma Reforger;
- run the unmodified official Mod on a non-monetized Arma Reforger server;
- share a link to the Mod's official Workshop page; and
- capture and share non-commercial gameplay screenshots or videos featuring the Mod.
No ownership rights are transferred. All rights not expressly granted are reserved.
4. DEPENDENT MODS ALLOWED WITHOUT SEPARATE PERMISSION
You may create and publish the following as Dependent Mods without obtaining separate
Written Permission:
- Arsenal, loadout, faction, scenario, mission, or server configurations that reference
the Mod without altering or bundling its files;
- compatibility addons that connect the Mod to another system through publicly exposed
classes, APIs, components, events, or supported extension points;
- reskins made from your own original files or from templates expressly provided for that
purpose by EvilJackk; and
- limited prefab or configuration variants created through inheritance, overrides, or
other supported dependency-based methods.
Every Dependent Mod allowed by this section must meet all of these conditions:
- The official Mod must remain a required dependency and must be obtained from its
official Workshop listing.
- The Dependent Mod may reference or extend the Mod at runtime, but it may not contain,
copy, extract, replace, redistribute, or repackage Mod Content or third-party material.
- The Dependent Mod must be published only through the official Arma Reforger Workshop
and used only within Arma Reforger.
- The Dependent Mod must use a distinct name and may not be presented as an official
version, update, replacement, continuation, or release by EvilJackk.
- The Dependent Mod and every server or project using it must remain non-commercial and
non-monetized and must comply with all other sections of this license.
This section permits dependency-based interaction with the Mod. It does not permit a
standalone fork or direct modification of the files distributed with the Mod.
5. USES REQUIRING WRITTEN PERMISSION
Written Permission is required before doing anything not expressly allowed by this
license. Examples include:
- directly editing or distributing a modified copy of any file from the Mod;
- creating a standalone, bundled, or dependency-free version of the Mod;
- substantially reconstructing or replacing the weapon's identity or core implementation,
including its rig, animations, sounds, scripts, or core systems;
- converting the Mod into a different weapon or using its implementation as the basis for
a separate weapon package;
- distributing project files, source files, development files, or private extension points;
- incorporating Mod Content into a mod pack, compilation, repository, installer, mirror,
or other package; or
- using Mod Content in a collaboration or project beyond the Dependent Mods expressly
allowed by Section 4.
To request permission, contact EvilJackk on Discord at @eviljackk and describe the exact
files, changes, distribution method, and project involved. Permission is not granted until
EvilJackk provides explicit written approval. Any approval remains subject to Bohemia
Interactive's applicable terms and all applicable third-party licenses. EvilJackk cannot
grant permission to third-party material beyond the rights EvilJackk is authorized to
exercise.
6. NO COMMERCIAL USE OR MONETIZATION
The Mod, Mod Content, and any Dependent Mod may not be used for any commercial purpose
and may not be directly or indirectly monetized.
Prohibited activity includes, without limitation:
- use on a monetized, sponsored, advertised, paid-access, or revenue-generating server;
- paywalled downloads or early access sold through Patreon, Ko-fi, Boosty, SubscribeStar,
paid Discord access, subscriptions, or any similar service;
- paid queues, whitelisting, priority access, ranks, roles, currency, items, equipment,
services, features, or perks connected to the Mod;
- donation goals, crowdfunding rewards, memberships, or payments that provide access to
or benefits from the Mod or a server using it;
- sale, rental, paid licensing, paid distribution, or inclusion in a commercial product or
service; and
- any arrangement intended to produce revenue or commercial advantage from the Mod,
Mod Content, or a Dependent Mod.
A general and entirely unconditional donation that grants no access, advantage, feature,
recognition, or other benefit connected to the Mod is not prohibited by this license to
the extent it is permitted by Bohemia Interactive's rules. Bohemia Interactive's approval
of a server's monetization does not exempt that server from this section.
7. ARMA REFORGER ONLY
The Mod, Mod Content, and Dependent Mods are licensed solely for use within Arma Reforger.
You may not port, convert, adapt, export, recompile, or use them in another game, engine,
software product, framework, application, platform, or environment.
No permission is granted for use in another Bohemia Interactive product unless a separate
written license expressly authorizes that use and the applicable Bohemia Interactive and
third-party terms permit it.
8. NO REDISTRIBUTION, REUPLOAD, OR REPACKAGING
You may not upload, reupload, redistribute, mirror, rehost, bundle, archive, republish,
repackage, transmit, sublicense, or otherwise distribute the Mod or any Mod Content,
whether modified or unmodified, without Written Permission.
The Mod may be distributed to users only through its official Arma Reforger Workshop
listing by EvilJackk. This restriction does not interfere with downloading, caching,
updating, or server-to-client delivery performed automatically by the Workshop and game
as part of their normal operation. It also does not prohibit a compliant Dependent Mod
that contains none of the Mod Content or third-party material.
9. NO UNAUTHORIZED EXTRACTION OR COPYING
Except where applicable law does not permit this restriction, you may not extract, rip,
export, decompile, decode, recover, copy, or otherwise obtain Mod Content from the
distributed Mod for reuse or redistribution.
This restriction includes, without limitation, textures, materials, audio, animations,
rigs, source files, scripts, configuration content, and other files created by EvilJackk
and distributed as part of the Mod. Permission to make a Dependent Mod does not authorize
the extraction or copying of any such content.
Third-party models and material may not be extracted, copied, redistributed, relicensed,
or reused through this custom license. Any rights in that material must come directly from
its applicable third-party license or rights holder.
Rendered screenshots may be used only as visual references for an otherwise permitted
reskin or for the non-commercial media use allowed by Section 3. They may not be used to
reconstruct or redistribute underlying Mod Content or third-party material.
10. SCRIPTS, ANIMATIONS, AND TECHNICAL SYSTEMS
You may not copy, modify, redistribute, repackage, or create a standalone derivative of
EvilJackk-authored scripts, animations, rigs, systems, configurations, or technical
implementations without Written Permission.
A compliant Dependent Mod may call, reference, inherit from, or extend publicly exposed
classes, APIs, components, events, prefabs, and supported extension points through the
official Mod dependency. This permission does not allow copying source code, animation
data, configuration files, or technical implementations into another project.
11. OWNERSHIP AND NO MISREPRESENTATION
EvilJackk retains all applicable rights in the Mod Content. No provision of this license
claims ownership of Bohemia Interactive content or material owned by another rights holder.
You may not falsely claim to be the original creator or publisher of the Mod, impersonate
EvilJackk, or present an unofficial project as an official release, update, continuation,
or replacement for the Mod.
12. DISCLAIMER OF WARRANTY
The Mod is provided "as is" and "as available," without warranties of any kind, express or
implied, including warranties of merchantability, fitness for a particular purpose, title,
non-infringement, compatibility, availability, accuracy, or performance.
13. LIMITATION OF LIABILITY
To the maximum extent permitted by applicable law, EvilJackk will not be liable for any
direct, indirect, incidental, special, consequential, exemplary, or punitive damages, or
for data loss, server downtime, save corruption, mod conflicts, software instability,
hardware issues, loss of access, lost profits, or lost revenue arising from or relating to
the installation, use, or inability to use the Mod.
14. VIOLATIONS, TERMINATION, AND ENFORCEMENT
Your rights under this license terminate automatically if you violate it. Upon termination,
you must stop using and distributing any affected Dependent Mod or other project and remove
any unauthorized copies of Mod Content in your possession or control, except where retention
is required by law.
Violations may result in removal or takedown requests, revocation of permissions, reports
to Bohemia Interactive or other hosting and distribution platforms, and legal action where
appropriate and legally available. Any copyright claim will apply only to material in which
EvilJackk holds the relevant rights.
Bohemia Interactive is not a party to this license dispute and retains its own independent
rights and enforcement authority under its terms.
15. SEVERABILITY AND NO WAIVER
If any provision of this license is held invalid, illegal, or unenforceable, that provision
will be limited to the minimum extent necessary where legally permissible, and the remaining
provisions will remain in effect.
Failure to enforce a provision in one instance does not waive that provision or the right
to enforce it later.
16. VERSIONING
This license governs the version of the Mod with which it is distributed or expressly
cited. A later license version does not retroactively replace the license attached to an
earlier Mod release unless EvilJackk expressly states otherwise in writing.
17. ACCEPTANCE
By downloading, installing, accessing, using, or creating a Dependent Mod for the Mod, you
acknowledge that you have read, understood, and agreed to this license.
