Raunhofer has released a new coop mission in the BI forums.

Quote Raunhofer :
This mission is inspired by Air Cavarly, it includes respawn and hours of playing.

Mission starts with a small intro action, so don't worry if you'r going to die at the beginning of the mission, the rest of the mission isn't so difficult

Second advance also includes a high command ability and it's playable with a small player groups too (even one player is enought).

This mission is tested with a large scale of players.
