To date I haven't been able to breach a UFO door with anything other than a C4 charge - rockets, heavy weapons, vehicle heavy weapons don't seem to do anything (even firing a half dozen times). I bring up the manual targeting mode (click on the weapon) and then mouse over the door until it has the open door icon. Is this a known issue? Am I doing something wrong? Is there anyway to debug? I'm running 0.99.45 Thanks!
