I think there should be a creation menu when your robot is made (color/name) and 3 class types theres the guy we have now a light armored but fast guy and a heavy armored guy and slow it would be cool if you could start with or buy weapons like spear a bigger sword mace and a shield to fight with. this is a arena game
ps I think that if both your arms fall off you don't die I know it could be a bit op but just saying its more realistic you could make it the more limbs that fall off the slower your get so you could have no arms but be super slow.
