Map: Mars
I like mars because because unlike maps like MoonQ20 it is square, meaning on a 2v2 you have to controll a much larger amount of land. This usually leads to it being hard to porc since you have to build a huge defensive line to make it so it cant be breached. All the hills just make this full of tactical positions. Lots of people complain that its too big for 2v2 but I just love it.
EDIT: cause i realised the real reason I like mars so much.
The size of the hills means that building a T1 defence structure on the buildable peak will not have the radius to fire on anything that isnt on the hill, ie the radius of a LLT wont extend past the slopes of the hill. This means hills are usefull for artillery and maybe anti air, but they dont restrict movement of troops going past them.
Unit: AKbot
I love spamming AKbots, to have an opponent send in a standard wave of rocket bots only to be swarmed and gridlocked by AKbots a fraction of their cost is just priceless. I also find them usefull on a more strategic level for taking intermediate land controll and lowering an opponents mobility by constantly harrasing workers and expansion.
