    Simply never use a different gun than you start with. It really isn't as daunting a task as it sounds considering that the plasma cutter is actually the most versatile weapon in the game. You can own the others just as long as you don't use them. Obviously, you'll want to max out the stats of the Plasma Cutter as soon as possible. You only need to worry about the stat increase nodes to max out a weapon. Only fill an empty slot if you need to in order to reach another stat slot.

    If you wanted, you could use the New Game+ feature to load an already beaten save file to do this run through with an already maxed out weapon. This is completely unnecessary though as you should have the weapon maxed long before running into enemies that are overly difficult to beat.

    If completed correctly, it should unlock just as the credits start to roll.

    RIVE XNGLEI am going to confirm that you are able to melee with other weapons.

    When I started my second playthrough, I did not have the Cutter in the beginning and had to swing and stomp my way through the first chapter. It was quite annoying, but necessary.

    Sandpiper121PPI used the Plasma Cutter thru the entire game and found it very easy being it is the best gun in the game in my opinion. After getting the achievement I went back and tried the other guns... and was not as impressed. wink

    An easy way to get this achievement is after you have already beat the game. Start a new game with your recent character and ONLY use the plasma cutter. I recommend doing this because you will already have known where everything is and what to expect plus some of your stuff will already be upgraded and you will most likely boughten some good armor. The plasma cutter is really the best weapon in the game it's versatile, powerful, and the ammo is cheap. Also because you are continuing a new game with your previously used character you can worry less about buying armor and you may already have upgraded your plasma cutter some. But use ALL of your Power Nodes to upgrade the plasma cutter and your armor. YOU DO NOT NEED TO FILL IN THE EMPTY CIRCLES IN THE UPGRADE MENU.

    You can ONLY shoot your plasma cutter, you can still use stasis and telekinesis. You can stomp and hit but the only weapon you are allowed to SHOOT is the plasma cutter. So if you accidently pull out a different gun and you don't shoot it your ok.

    Good Luck I don't recommend doing this on Hard or Impossible.

    MarkuuusPretty sure when upgrading a weapon each slot must be filled with a power node, whether they lead to an upgrade or not.

    I got this from a New Game + on Normal difficulty, with a maxed out plasma cutter.

    you can have other guns in your inventory, and even upgrade them towards your "maxed out" achievement, but don't fire them.

    It's wise however to drop all weapons apart from the cutter into storage, as the game will give you more plasma energy from enemy drops, which is the only ammo you want. if you do happen to pick up other ammo, sell it, and buy more plasma ammo, or nodes to upgrade stuff you haven't already.

    *NOTE* using the ships defence cannons do not disable this achievement.
