First I thought this was hard, I was wrong =3 is just awfully slow. But it's loads of fun and all badges are easy. Just summon soldiers, 1 signaler, 1 field medic and then keep up for grounded guns. Hide'm all behind something and the badges are yours
REALLY GOOD TIP: If you have (preferenciably) a power metal song, let it play and just go inputing the lyrics. You'll get many in no time, and don't wait a word to be shot, just keep typing and pressing enter after everyone
Bad, poor, too long, too boring, -10 for being a bad rip-off of frantic, the background is bad, there should be more ships, didn't deserve badges. Just repeat lvl 4 in the beggining and then 10 forever and lvl up everything to the max. You'll destroy the bosses like 'huh? what? already?'
I really don't get it, it seems like a Magic The Gathering half-assed rip off. Didn't like it really. And my 'Best so far' for the medium badge won't change.
For the key, go all the way to the end, than go back, jump up the plataform that is like a staircase to the highest part, but do not go up already, go plataform by plataform and search for the key, for it's really near. As soon as you find it, don't worry about getting killed, it's always in the same place.
