Metal Arms: Glitch in the System Cheats for XBox
In order to beat the Zombiebot King use rockets to reduce his energy wait until he doesn't move then throw a grenade (coring charge) into its mouth. On Normal, it takes five grenades to kill him and after the 3rd and 4th grenades there are regular zombiebots that swarm the arena.
On the level (tanks a lot) when you are being a titan, you can warp to random parts of the level, just by going to the tower and going up the right part of the level, jump up on top of the trash can and going to the edge. When you kook right there should be a gap fall in (as a titan) and you shoube stuck. It should take about 5 secondsbut you will fall in random parts of the level try falling in at different stots to got to different places.
To do this you have to have 2 people playing. Don't have the "Bot State When Not Tethered" on. Get one of the players to a loader and hover over where another player should be standing right behind the sentinel, with the control tether out green and have them fire it. The exact time they fire it the player in the loader should grab the player who fired the tether, then the loader player should keep holding down the right trigger and fly off the edge horizontialy, don't hit a wall or it won't work, when the loader player kills himself, the sentinel should fly off the edge of the cliff. When he/she dies, they should appear a little higher off the ground all the way down at the bottom of the cliff. Then your can just run around there. Oh, and the other player can keep jumping down the cliff with the secondary weapon as a hand and the primary weapon as any gun the player at the bottom of the cliff wants. It works the same way with empy primary and equiped secondary hands. Hope it Works!
During the multiplayer level tanks a lot, get the loader and go on top of the bridge where there is a titan next to you, go in the center of the bridge. Jump onto the loader and tether the titan, make the titan quake next to the loader, you should be in the air in pieces.
