Any1 know how to defeat this boss. I didnt get the 'grenade-gun' (or what it's called) and everytime I get close to take his health down a good amount, he jumps up and 'reloads' his health again.
I have 4 grenades, 1 health pack and the automatic gun (forgot the name of that too).
Any help would be very much appreciated.
