NDS games similar to Metal Slug

Hi :)
It really blows that the Metal Slug 7 for NDS does not have the multiplayer function..
Can anyone recommend games that are similar to it, I want to kill some time with my friend playing those types of games :P
Thanks

Commando Steel Disasterand the upcoming Duke Nukem games
