I chose the most ridiculous names and created a server just to try this, and for maximum effect, sudden death was on. As the bodies piled up, they kept blocking shots, which led to amusing results most of the time. Also, we found out that spectating and entering the game again left a body, too, so I was able to make a skittles rainbow of animals at the base of our corpse tower. also, the moving platform in Meadow Match, when corpses pile up high enough, crushes you. I had no idea it would until it happened.
It was amusing watching everything pile up, although the names can be a real big problem, making it too hard to see. Holding the scores up seemed to be the only saving grace.
Anyway apparently the corpses can jam crushers, which lead to some wonderful results.
We later played Mystic Realm (No screen shots of it) And had a funny encounter when getting to Rainstorm Keep Zone. We tried going the original path (The fast way) and the crusher surrounded by goop got jammed. We tried to get through it but couldn't so a bunch of bodies were left there. So, we unanimously got this idea to take the other path, and I managed to get through deathless.... but my Tails friend wasn't so lucky. He got the gigantic crusher jammed... but was able to spin through it. The bodies impeding the path were funny, because it actually made that crusher section easier for Tails.
Also, there was a Sonic, Shadow, and Tails skin for Skulltag/Zandronum.. and they too died horrifically when killed. Oh, and they were ripped straight from SRB2.
