This game was released for free via Steam a few days ago, and is a remake of an old Unreal Tournament mod. It's a sci-fi top-down game that has an emphasis on team work, a bit akin to the game mechanics of Left 4 Dead. I've just finished playing through most of the first campaign, missing a few of the beginning levels, and it was pretty fun.
There are four classes to select. Each with their own special bonuses. The Officer offers damage dealing/resistance bonuses to the 4-player team. The Special Weapons generally specializes in bullet hose dakka action. The Medic, well...heals. And the Tech can hack through doors which would otherwise prove inaccessible. In some cases, the Tech class and certain weapons are mandatory to complete a level.
Each class has two characters to choose from, allowing two of the four players to use a class simultaneously. So there is a low chance your favorite class will have already been claimed as soon as you enter a game lobby. Though as I've said before, the Tech class is sometimes a mandatory slot to fill.
Unfortunately, there is only one campaign available to play as of launch. Though the game was released alongside with mod tools for users to create their own. So it can be anticipated that there will be many, many more on the horizon. There are 64 achievements to be unlocked, as well, and the game allows your account to level up the more you play. Which in turn unlocks new weapons and equipment.
Bottom line, it's a solid arcade spirited game. And it's free. So I recommend checking it out if you're in to sci-fi, team work or simply enjoy shooting the crap out of things. Those familiar with Left 4 Dead should feel quite comfortable with the way the level progression and lobby menu is designed, as well. Though I must admit I wish there were more variety to the monsters encountered in the game.
I'll be playing this a lot, I'm sure. Rocking the Officer known as Jaeger whenever possible. So if you see me 'round on Steam and you wanna play, I'd be happy to oblige. My Steam ID is: Mjolnir73
