Dude! Where's my Warthog?
I refer to the dumpster trap on Foundry, where you put a dumpster in an enclosed hallway, and then put a Cannon Man behind it, a Custom Powerup in front, and a teleporter receiver on the top to hold it down.
I have tried to create this on Sandbox, but I can't seem to find an object to replace the dumpster. Discuss.
