If you've been following this blog at all, you'll probably have noticed a board game centric take on gaming. Game sessions is a broader topic than just board games. If you just want board game posts then look for posts with the label "board game": this post is labeled "console game".
Two tanks roll into base. I've got a rocket launcher but only 2 shots left. I duck for cover. Overhead a dogfight is raging, no air support. I run to the wall and climb up to a mounted machine gun. I unload round after round into one tank, but then its turret tracks toward my location. I jump away from the gun, run up a walkway right over the tank. The gun has been destroyed. I grab a wrench and drop onto the enemy tank. Two more hits from the wrench and the tank is gone. Too bad the other tank gets me in its sights then.
Warhawk is about conflict between the Eucadian (blue) and Chernovan (red) forces. There is some back story about Chernovan's invading Eucadia, but you have to look hard to find it. The zone mode is a game about 2 teams with up to 16 players on each team fighting to conquer (or defend) territory.
Warhawk doesn't seem like that much on paper: only 5 different maps, no single player mode, no bots.
Warhawk is my favorite online game. This game has something for everyone. I really enjoy big games (20+ people). But there are people who enjoy small (2-8) team death matches or flying capture the flag games or 4 player split screen death matches or even just jeep races (not an official mode, but that doesn't stop people).
It does support up to 32 players in 4 different game modes. And each of the 5 maps has several different layouts. There are infantry, jeeps, tanks, and aircraft. Both grunts and planes have weapon pick-ups.
I frequently host games using the PS3 as a dedicated server (how cool is that). Feel free to let me know if there are any game types that you don't feel have enough dedicated servers. I'm currently hosting a 12 player flying capture the flag game.
