There is this game called "Half dead". I'm sure there are other games like it.

Here's how it's played. There are many identical rooms all around you. You go from room to room, trying to find the exit. But each room can have a different trap, some more deadly than others.

It has multiplayer too. You can be in a team and try to reach the exist before the other team.

Now imagine that for spiral knights.

Each square room is surrounded by 4 other rooms.
-You make your choice, you go in, you press the button in the center and hope for the best. Let's say, the doors close and 4 rocket puppies spawn in the 4 corners of the room. Great, you deal with them, you move on.
-Next button, does nothing, great!
-Next button, spawns Roarmulus twins like alternating lasers for 10 seconds, and you have to dance around them.
-Next button, spawns a perma alpha frostifur that will follow you around till the end of the round. That sucks. Deal with it.

That could be really cool. And it's can be team based. 2 to 4 players on each team. You can each go in separate ways, or stick together in hopes of fending off the traps and challanges faster and better.
