Hello everyone i think i have reached my limit
during the campaign bots have reached 500+ HP
meanwhile my best torso has only 288 hp,
i feel out gunned and out matched at this point,
I have used my 40 win golden box already and i got nothing of value
Any way to get a better torso and not die in 3 turns to these overpowered bots in the campaign?

Unfortunately the only way to get a torso good enough to beat the campaign bots is to open silver/gold boxes. SuperMechs is a free to play game yet costs the developers lots of money to maintain and update the game. As such, they rely on people buying tokens for the majority of the money they make. It's the same with practically any free to play game. You CAN get the good items as a f2p, but it takes a lot of time and effort. You just have to be lucky with boxes.

Hope this helps.
