One thing me and my friend have noticed during our obsession over pterattack was that the grarrl only comes up every time yoyou hear that “muahahahaha” on your speakers. It always comes 1 to 5 seconds after the “muahahahaha”. So every time you hear that evil laugh, move to the middle of the screen until you seee the grarrl and move AWAY from it.
Guns and Upgrades
If you are a beginner:
– don’t get every circle thing (gun upgrades) you see. Every time you get a different color circle, you start on the lowest level of that gun. always stick to one color of circle things.
