BIG improvement!
This game was far more balanced than the first! In the first game I couldn't make it all that far, in this game though, I managed to get to the "end" of it (30 silo guys, 50 gunmen, 60 workers, all the guns and so on) at medium. Though I guess I could've been lucky with what I upgraded after each level.
The weapons were AWESOME. In other games, the handgun is usually the next best of the normal weapons, shotguns are the worst, and automatic weapons the best. But in this game it's different, here the shotgun is more powerfull than the handgun, and the grenadelauncher actually is effective even though it has a slow rate of fire. And the gravity gun just ROCKS (wish it could take more enemies at a time though).
The only "bad" would have to be the anti-tank rifle, as it really fires too slow and costs too much for the damage it does (by the time you get it you'll have to click your fingers off in order to kill anything).
The sound is good, fits the weapons well.
The graphics are very functional (just what this kind of game needs), and my computer didn't lag even at the last level I played, something most games cant say for themselves.
The interactivity score speaks for itselves.
Humor is for the fun of throwing tons of people and hardware in the air with the gravity gun.
Overall, an AWESOME game, it's on top of the defence games sharing first place with "Defend Your Castle"!
