True, it pretty much butchered what was left of the JJ franchise from the business standpoint by changing almost everything around, but it's still a pretty solid game, with some decent new weapons, music, and a single-pak 4 player multiplayer mode that's actually quite fun compared to the other crappy and/or boring after a short time single-pak multiplayer games on the market right now.

Also, the Castle tileset from JJ2 is used in a few levels
