Wow...the zombies got stronger and stronger that in the end they become invincible...that is, if you get bored enough to gather all your resources to the last bridge and not detonate the explosives :P
Get all money, don't get hit, don't alert the enemy, and don't kill anyone for a huge bonus. I got 13K like this on level 1. Didn't even have to try hard to get the remaining 2000 points in level 2...
I think the game made the turret semi-automatic so you can decide the pace of your turret (important if you don't want overheating). However, it would be nice to have an complete auto option.
At least now they tell you the system is under maintainence...better then going "WTF!? LOST CONNECTION AGAIN!?"...although that means we still can't play :S
Everyone who is wondering about the fuss about the game being stolen see r00ntie's comment and rate it up for the sake of understanding the argument and shutting everyone up.
Just saw a weird glitch. The hero came out but the intro wouldn't stop. I pressed skipped and he just got stuck all of a sudden and said "ARGH! Let me go!". Then my archers slowly consumed his health. Epic fail?
