Imploders are ridiculously powerful, ROF should be lower. Also, how about leveling units? That way I might even feel bad for the redshirt nailgunners in the front lines. :)
Walkthrough: 1. Press C and keep it pressed!, 2. Press right and keep it pressed 'till you reach the right end of the screen. 3. Press left and keep it pressed 'till you reach the left end of the screen. 4. Repeat from step 2. Fun game though.
It gets pretty easy once you could kill a lvl300 monster with a double slash... and it doesn't have an achievement for having every pet :-) because of this and the spelling errors: 3/5
I know it's called 'Endless Zombie Rampage 2' but at least the campaign could have an end... some REALLY tough bossmonster which requires your braaaaaaaaaains to kill, then some cinematic... whatever good game. 4/5 for the lame ending.
