Despite their game being over a year and a half old, New World Interactive continues to provide free Insurgency content to their core fanbase of tactical FPS gurus. The game, which you can think of as a midway point between Counter Strike and ARMA, just received its most recent batch of new modes, weapons, and maps.
The new update, "Conquer", brings with it a massive cache of changes, so here are a few highlights:
SteamOS and Linux support The Conquer cooperative mode, which tasks players with controlling three points scattered around the map while simultaneously searching for enemy supplies to destroy Greater behavioral complexity for the enemy AI, from an understanding of cover and retreat tactics to a new targeting system New map, Kandagal, and a revamping of the Contact map to include day and night versions New weapons, such as the Galil assault rifle, the Sterling sub machine gun, and the Model 10 revolver The ability to "cook" grenades and plant C4Of course, the update also brings stability, performance, and UI fixes, which you can parse through using the link above.
If you haven't had a chance to test your tactical-ocity in Insurgency, it's currently available through the Humble Bundle. The game supports eight player online co-op, so this is also a good chance to pick up a few extra copies and fill out your squad. Trust me, you'll need it.
