This is an idea for a game that will utilize MechaSource's online fuctionalities and achivement system when it comes out. However, since it is a idea at the current state, I won't start working on it straight when MechaSource comes out. Perhaps after I've actually made a decent game.

Anyway, here's the idea: A mix of Super Smash Bros with generic fighters with DOOM's demons as characters. Basicly, think of MFGG Royale except with a slightly different system and more emphasis on aiming (atleast, you're not stuck with aiming forwards) and timing with melee, (yay combos!) as well as using each demon's abilities instead of having copy paste clones with different appearances with minor differences.

For example, the imp, with his really humanoid appearance, can leap, roll, and grab on to ledges with a decent speed and jump, as well as a decent projectile and decent melee combos. The melee-only Demon similarly can leap but not roll or grab onto things, but he can sprint, charge, and lunge with a better jump and base speed, as well as fast meleeing. However, since he lacks a projectile, he lacks the ability to do long-range combat. The final example I'll give is the Hell Knight, which is slow, can't really jump, and can't really do anything. However, he has a powerful projectile and a very powerful but slow melee.

I'll probally not be able to do Archviles (their attack is, well, just too powerful), Pain Elementals (they shoot lost souls and it would be stupid to have to spat out ones just charge and explode when they hit something), Baron of Hell (I already have Hell Knights planned to be the Hell Noble), Cyberdemon (dude, it's HUGE), and Spider Mastermind (see Cyberdemon). Also no Icon of Sin unless you want to play as a wall. :P

Also I think I should mention that the game will be very bloody with gore shooting out everytime you hit a bleeding (aka not lost soul) opponent with something that should cut the skin, as well as, if you do enough damage, the enemy exploding into ludicrous gibs with guts and gore everywhere. Happy fragging!
