It's a game that is easy to play but hard to master. Defeat the red team to increase the rating and work your way to the top of the leaderboards. Each victory yields a skill point to be spent on various upgrades on units and structures.
Kill the mutant monsters that want to eat you by shooting them down or throwing grenades. Don't forget to upgrade or buy new weapons to get more firepower!
All your team members are dead and you're the only one survived. Just stay alive as long as you can and don't forget you are low on ammo, use 'em wisely.
Play as war hero on a mission to survive the enemy attacks. Shoot your way through 10 waves of enemy assaults, unlock 12 trophies and try to beat the high score.
