This is what you'll need for this trick:

- a plasma grenade (in Covenant weapons)
- a wall (any type of wall)
- two players

You must be on Xbox Live for this to work!

Step 1: place a wall anywhere in forge world (well not in the ocean, lol).

Step 2: get rid of all your ammo and grenades (this is required).

Step 3: place down a plasma grenade.

Step 4: walk up to the wall and throw a plasma grenade on you.

Step 5: quickly go into forge monitor.

Step 6: have your friend leave the game (the screen should go black and say connecting to new host or something like that).

Step 7: go to human (if you're still in forge monitor).

Step 8: have your friend rejoin the game.

Step 9: have fun!
