How to defeat the Zombiebot King:
To defeat this boss you must use your Rocket Launcher to wear him down until he stops attacking and rests to try and catch his breath (yes I know its a robot.) Whilst he has stopped attacking, either throw or use the slingshot to catapult a coring charge into his mouth. After the third time some of his minions will come after you, take them out and then throw a coring charge in his mouth again, more minions will come after you again. So despatch them and throw or catapult the fifth and final final coring charge in his mouth. (You can tell if the coring charge has worked because he roars after the charge has exploded in his mouth.)
General Corrosive first encounter:
When you face General Corrosive in the arena, you will have no weapon, and for a reason (he is practically in-destructible). There should be 3 or so box scattered around the arena that are partly see-through with a health inside as well as a Spanner. Hide behind the box and trick General Corrosive into destroying it, and when General Corrosive blows it up with his rocket launcher, take the health and Spanner. Now you can equip the Spanner in your left hand, when it is equipped run to one of the make shift shelters and disassemble yourself. Then all you have to do is let General Corrosive blow up the shelter and see you in pieces.
General Corrosive the Second encounter:
When you are on the Space Station and you come across General Corrosive (Only god knows how he got up there) you will find out that to operate him you need 4 chips for the console at the top of the big tower. The first chip can be bought from the barter droids for 150 washers, to find the barter droids you need to go to the top of the big tower in the middle of the area. >From there you need to drop down onto one of the 2 bridges and make your way to the 2 elevator like arms constantly going up and down. Once you have gotten to the top on the elevator arms jump off and llok for the barter droids in a small sort of cave/hidy hole.
Buy the chip from them and then take it back to the console and plug it in (try and avoid General corrosive or you will be squashed.) At the bottom of the tower there are some arangements of boxes all around the base,blast them to find another chip. (Rocket launcher is good for this.) Take the chip back to the console again. The third chip is located 45 degrees to the left of the tower as you are looking at the two lifts going up and down, it should have a health and a speed artifact near it as well. The last chip is located to the right of the tower as you are looking at the two lifts again (wait for it) 135 degrees right from the lifts to be precise. (Note: AVOID GENERAL CORROSIVE AS MUCH AS POSSIBLE! and to understand the writing above you must be good at angles.)
