Ahaaaaa! That explains it! Haha, well they killed themselves and the enemy then. Maybe i didnt catch a text in the tutorial and missed that mechanism. Damn :-)

Yeah, there's a part in the tutorial talking about how tanks overheat if they drive or shoot too much. This isn't really that big of a problem later on though, because bigger hulls have much better heat tolerance. So once you unlock them, you can do a lot more before you have to stop and let your tanks cool back down.
