Action 52: The LJN Library is a Nintendo 3DS game that includes 49 out of 56 game's by LJN and 3 new ones created just for the games library. While Cheetahmen 1 & 2 are waaay better remakes of the original Nintendo and Sega versions, LJN Rumble is a brand new game featuring 21 fighters from 12 different LJN games.
The Lego pictures are just for show, and not apart of the game.
The only LJN games that are not included are Bill and Ted's Excellent Game Boy Adventure, True Lies for Game Boy, Alien 3 for Game Boy, Alien 3 for NES, Beetlejuice for Game Boy,Crash Dummies for Game Boy and Crash Dummies for NES; & that's because they are waaay too much like their counterparts that did make the cut.
So far, this is the only sequal to the original Action 52 back in 1991 & 1993.
This marks the return of The Cheetahmen.
The unplayable final boss of LJN Rumble is named Chaotus.
All of the WWF games were renamed WWE, for obvious reasons.
