Purely fun-oriented alien wave shooter that uses spectacle and scale to make up for what it lacks in depth.
+ endearingly stupid dialogue with iconic voice acting (special shoutout to all the incompetent army command transmissions)
+ constant escalating battles giving a rather authentic war impression
+ excellent mindless multiplayer experience
+ hundreds of distinct and powerful weapons
+ fittingly grand soundtrack
- barely passable graphics
- pathetic mobility for three out of four classes
- no progression sync between local and online modes
- no weapon drops for other classes preventing spontaneous switching
- significant mission bloat with repetitive enemies and forgettable objectives
