To get the trophy on the stage where it tells you to go to the right (the stage is just a like the beginning minus the spikes but no trophy that means you are to far) GO TO THE LEFT
Wow, you know the devolper just tried to wrap things up when he doesn't even use the stone guy at the end, kind of a good game lol check the badges like 3000 people got off the planet without leaving the ship =)
To easily get the 500 headshot badge you will have to use the 99 ammo hunter rifle glicth. Step1: Equip chainsaw as main weapon and Hunter rifle as Backup Weapon. Step2: Hold down the trigger button with the chainsaw. Step3: Press SPACE and you will equip hunter rifle with 99 AMMO! So now its like non-stop bullets! GOOD LUCK WITH HEADSHOTS! keep it going
