I've been playing for a long time, and I have had this idea for a while. A new floor or group of floors that have a much harder twist to it.

The said floors would be completely dark. I don't mean "Oh, I can see the edges of the walls " I mean pitch BLACK beyond light sources. The radar would be jammed as well, except for seeing your allies dots. At the beginning of the floor there would be a small light generator. The generator would cast a ring of light around it, about the radius of a Nitrome blast and acts like a statue.

The only light sources would be from torches, with no permanent light sources anywhere except for the elevators. Being outside of any light would cause low periodic damage. All enemies and items would not be visible unless they are within a light source.

The enemies on the floor would also be completely random, so that a wide range of weapons are needed for any possible encounters. This would make coordinating your equipment with your allies vital.

The idea of the floor is that the knights will have to carry the generator with them throughout the floor. This would take a high level of teamwork, deciding whether to have one knight carry it during fights so the others can have a mobile light source, or dropping it and having to fight in smaller area.
