Two Fronts - Lions Roar

Lion's Roar is a structured co-op campaign for the Two Fronts map.
Spawn at the main base and gear up at the staging square. Form squads and move out together, on foot, by vehicle or with a player pilot.
The campaign runs in Operations. Each Operation takes up to three nearby sectors on one front, one after another, with no waiting in between.
Required tasks are marked [!] on the map. Optional tasks are there for any squad that wants them.
When the last sector falls, the force pulls back through a marked border crossing, and the next Operation starts on the other front.
Expect car bombs, suicide bombers and counter-attacks. After a capture the enemy sometimes regroups, and the squads hold the sector for fifteen minutes.
Enemy rockets fire from launchers hidden in each sector: hunt them down to stop the salvos.
There are no points and no rewards. What counts is what your squads take and hold.
The campaign is saved and survives server restarts. Built for small groups first (hard for 3 to 8 players) and scales up to 30.

Requires the Two Fronts map. The server runs it with its own mod set.
