As much as this may seem stupid...
HOW THE CRAP DO YOU BEAT ALIEN HOMINID ?!
I can get up to the last boss with all of my lives... the one that says do not injure head and has a massive canon and fist. But then WHAT !? Everytime i jump onto the canon to reach his head and shoot it, his fist clobbers me, same as if i go from underneath.
How do i evade or destroy the fist ? PLZ I CAN'T STOP PLAYING THIS UNITL I BEAT IT !!!
