This game is really fun. I enjoy playing it with friends. If you try to go at it alone, you're ♥♥♥♥ed. This is like Team Fortress 2 with aliens and ♥♥♥♥. You should download the game as soon as possible and come to me to hear me scream like a ♥♥♥♥♥ when I get swarmed. Even if you have 3 other teammates helping you out survive the swarm, it can get difficult at times with different types of aliens that drop down from the sky to lick your ♥♥♥♥♥♥♥. There's different classes too, though you will always need a medic on your team, since there's a type of alien that infects your character, and can only be healed by a medic. If you play aggresively, try Vindicator. They can drop ammo and use chainsaws and all that ♥♥♥♥. Engineers can drop sentries, big surprise there. You'll unlock more as you progress through the levels, the level cap being level 30. I think I'm at around level 15-20. Don't remember. Go out there and kick some alien ♥♥♥, ♥♥♥♥♥es!
