Aftermath:

I hit unpause and the wallbot unscrewed itself and became an actual robot again... except it spawned below the arena and got OOTA'd after a few seconds. I don't know how the fourth robot managed to warp above the ground but whatever.
Here's what I did:
1. Downloaded this (http://web.archive.org/web/20050215104725/https://gametechmods.com/lu-tze/files/lt_joust_arena.exe)
2. Threw it into stock
3. Select 4 bots for a battle royale match
4. Switched it to death match
5. selected AA joust arena
6. Ignored the third tab, hit pause and then play
7. Wall of bot
It seems to only work in this arena, on light stock bots with plastic but I haven't actually really tested it that much.
