challenge tower, test your luck, and chess kombat. Puzzle kombat, but different and improved would be cool too.

This game needs Challenge Tower or something similar.
Challenge Tower gave me something to do after beating the Story.

Then there's Test Your Luck.
I loved this shit. It puts you in random match stipulations. Soooo much replay value had from this.

Last but not least. Test Your Might, needs to return DURING ARCADE LADDER.

I liked that Super Puzzle Fighter game from Deception.

Chess Kombat was fun as hell, it would be nice to see that come back but I hated Puzzle Kombat.

Yeah, chess kombat had great potential. And now that MK went back to 2D I would love to see it return.

Puzzle Mode. It was really fun and the music was always kick ass to listen to.

I also wouldn't mind Test Your Luck to come back, but what new features would you add to it? I can't think of any on the top of my head, but I really don't want it to repeat the things they had in the last game.

The "test your" concept from MK5 that never made it

I feel like Chess Kombat online would be so much fun, if it comes back I'd love to have it. Motor Kombat needs to never return, ever. King of the Hill was fun I wouldn't mind that making a come back either.

If challenge tower comes back, it would be funny to have a few carnival game missions on it. Like Reiko whack a Quan Chi. There would be nine holes and Quan chi would appear randomly from one, along with a bunch of Oni. You would get koins for every oni you smash, and lose koins if you hit a dragon. The mode would be timed, and if you get Quan Chi you get a ton of tokens.

Another would be Darts with Skarlet. Use her knives as darts. And then bust-a-move with Kai. You would have to do a few dance moves as Kai. All of these of course would be the gag missions on challenge tower.

I would like to see less mini games and focus on the online connection quality.

I would realy love to see Test your might returning. It's the most classic.
Chess would be a realy nice ad because it was fun. Butt let NRS do the fightingsystem first and then concentrate on the extras.
