The team at Midway and indeed, the makers of the series: Mortal Kombat have decided to release Ultimate Mortal Kombat 3 on the Nintendo DS. As a bonus, they've implemented the Puzzle Kombat feature from MK: Deception here too. There are one or two trailers for this to look at.
To be honest, I reckon they imposed images from Ultimate Mortal Kombat 3 onto a DS screen in order to make the trailers. In a recent interview, Ed Boon is quoted to have said that the DS version will have online play for both UMK3 and Puzzle Kombat. This is all good and all, and having Puzzle Kombat is certainly a bonus and a half. There is another thing they need to do though.
He also said that they're using the Arcade version of UMK3 as a source. This is also a good thing, but I seem to remember that there was a version, namely Mortal Kombat Trilogy, which has just about every single character in the MK universe up to Mortal Kombat 3. It would be excellent for them to include as playable characters: Goro, Kintaro, Motaro, Shao Kahn, Chameleon (both versions), and the older versions of previous characters. I've noticed that only one character in the whole MK series has never been playable however, and that ironically is Shang Tsung from MK1! (Old Wizard!) If UMK3 for the DS is to be successful, it needs to offer more in the actual game than the 360 version, and more characters, new fatalities/animalities/babalities/friendships, and secrets (maybe via the characters!), are the way forward.
