User Summary
Aliens have invaded and wiped out most of the world's armed forces. Into the breach step a pair of swashbuckling action heroes, armed to the teeth with a wide variety of uber-powerful weapons. In this third-person science-fiction shooter, you play one (or the other) of these characters, defeating waves of alien enemies across multiple post-apocalyptic levels.
The game features multiple upgrade options - both free and paid - including weapons, level-ups, ammo, and even costumes for your characters. Gameplay is extremely simple: shooting is automatic, so all you have to do is move your character to the right location and choose his/her weapons and special powers. But that doesn't mean the game is easy! As you advance in levels, the aliens become more powerful and more numerous.
