Woot, I've completed the final alien mission twice now, didn't get any easier the second time :O
But seriously, I've completely 100%'d this game. Got EVERYTHING. Guess it's just enough fun for me to come back to it.
After what must've been about 50 tries, I finally completed the final alien campaign level. Mostly thanks to a guide that recommended holy grail among other things, I managed to get an awesome killing spree that led to my win. Awesome stuff, 5/5.
That was quite the nostalogic playtrough. It's been a while since this game brougth me to knogregate. Flash games really helped me out by getting me trough a very boring phase in my life. And this game is to thank for helping me find them. Thanks to everyone invlolved in creating this game, and to whoever uploaded it to knogregate, and also thanks to knogregate itself and it's staff for existing. I'm grateful.
Getting that achievement was incredibly frustarating... I don't remember when I last felt such intense, agonizing, frustaration. But the feeling of getting trough lvl 50 was awesome...
