Teleporter Testing was just something I made when I was bored. It uses teleporters to launch people around the colosseum. It is pretty chaotic with more than one person. Example: YouTube - Teleporter Madness I recommend using a game-type where people can't kill each-other, and that death is impossible. Bottomless clip on things like the spartan-laser make it more fun too. Check it out, it's pretty fun!
This looks like it would get boring quite fast. You should make some sort of objective for the mode. You may want to spice it up a bit with aesthetics.
Yeah it can, but it is still fun to get flung around the map pretty quickly! If you play on slayer and tell people to only shoot when they are flying, it could be fun too! Or maybe even just use grenades!
