I would admit, when i first started playing i was noob galore. Then, now look at me. Using all the bassy techniques. The hat, the meatshield, the wallslash, the grab turnaround, the gas and i think thats all. Just my main advice for a dretch

would be when running at enemies, move right and left and jump and walk on walls and jump off walls when running at an enemy to be a matrixdretch.
And another thing: dont buy grenades. They arent what you think they are/
and last before buying an expensive weapon, buy armour. Armour > weapon, because a riflesuit can kill about 3 or 2 dretches aand live to tell teh tale and a "naked" (no armour) lucifer cannoneer can kill about 1 or 2 dreches before blowing themselves up or being overswarmed.
