What's a good tactic for situations where 2 or 3 teams both try to establish a base on the same plot? What I've been trying to do is start by digging my brain dude into the ground and letting the enemies come to me, but that almost always results in me getting destroyed. If I don't start that way, I can't buy things fast enough before the enemy finds me and kills me.

I need major help, because I'm starting to think I just suck at this game.

Honestly sucking at this game makes it more fun.

If you just want to win my top tips would be:

-Suicide empty rockets at them
-Take a minigun and spam offscreen in their general direction
-Snipers

Or you could try loadup dropcrate with molotov cocktail and some grenades and bomb everyone who gets close to your digged to the ground brain. But that wont win you a game, the best thing to do is get some reiforcements as fast as you can, and order them attack while your brain is digging for gold.
