The game is totally unbalance. Some heat weapon produce heat damage but lower your max heat pool in a really exagerated proportion. And in bonus, the weapon didn’t have maximum number of shot. So on the second turn, the enemy just shut you down and it’s impossible to cool down, even when you boost your heat pool and cooling. Kinda frustrating. there is no “tactic” in that, only abuse.
Can you show me which heat modules you carry and which torso you have?
