TomTaz just mentioned weapon catching and Jordanman mentioned projectile explosions. I had both things covered in this thread which I posted before. Here it is again. Some of these ideas were taken out and used in a few previous threads I've made so you may recognise some of the ideas.

Here are some ideas for MK6 I had. Given the extent of some of them, they’d probably never happen, but it’d be cool if they did. This is pretty long! Weapons should be able to be thrown. For instance, Kitana's fan throw, even though it used to be her special move, they turned it into her impale. If it missed, or was blocked you lost the fans. On walled stages, the fans should get stuck in a wall allowing for an attempt to retrieve them or maybe even have the enemy get them and use them. I suppose throwing swords and stuff would work as an impale or it could be implemented as doing a chunk of damage and shaving the enemy maybe. Also, they can be thrown low.

If weapons can be thrown, then obviously your going to want to stop them from hitting your. Basically, if it’s thrown low you can jump over it. If thrown high then you can either block (although that’s not realistic). I also don’t like the idea of sidestepping. That makes it too easy to avoid! In this case, three defensive maneuvers can be put in. Firstly, the opponent can deflect with their own weapon if they have it out and knock it out of the air to the ground. Secondly, they could dive out of its way in a given direction or thirdly, spin around the weapon and catch it out of the air if they are unarmed. Therefore, you have a defensive move for whether your unarmed or armed. The second one can be used in either case.

In the case of arena damage, I think that projectiles should cause explosions or craters depending on what you hit. The explosions would deal damage to both characters. Instead of sending a fireball at the opponent, you could aim it so it hits the object near them causing an explosion that causes a lot of damage. We’re in 3d now, it should be able to be done. If your caught in the blast, of course you’ll take damage too. Other special moves should also trigger explosions and stuff from vibrations and other stuff. In MKDA they had the statues being destroyed, so they could be used to inflict damage by their flying debris as they crumble, but you’d also risk hurting yourself if you hit them from a distance. Two projectiles hitting each other should also cause a minor explosion, causing slight damage if your caught in the blast radius and maybe even knocking the opponent back knocking them off guard for a second or so. It’d also be cool to see the characters cutting down some structures with their weapons as they hit them, doing gradually increasing damage until the object breaks or collapses.

Also, falling through floors would be great or if the ceiling collapsed on the opponent. For instance, Sub would freeze the ground in front of him and then you’d have to smash the floor with another attack to fall through. but you’d have to fight off the opponent before they smash it. In the case of the freezing, the surface would now be slippery. Falling through would cause the falling character (the one who didn’t break the ground) some major damage. Projectiles could be shot at the ground opening up craters to fight in or aimed at the ceiling to have rocks etc fall onto the enemy. If you have any ideas, please post them.
