A very uninteresting experience from a single player perspective.
The campaign starts without any kind of introduction or whatsoever, and it basically throws you right in the middle of what seems to be an insect armageddon. From there you simply go from point A to point B, killing insects and completing very basic objectives.
Now this game wasn't obviosly made for someone who is looking for a good or even a mediocre single player experience, but still, even some basic gameplay elements feel weak. The shooting for instance feels terrible. Guns simply don't give you the feeling of firing a gun.
The graphics aren't that bad, but they aren't anything amazing either.
Long story short, this game feels like a bad PSN/XBL budget title that nobody cares for. Feel free to try this game out if you are into co-operative gameplay and such, but don't expect anything ground breaking.
