When the game is over, the player may choose to rewind time to just before the final boss, or continue to "Challenge Mode" (a feature that was in the older R&C) where you get to keep all of your weapons... except now, you get to UPGRADE them farther! Enemies get more challenging, etc. Multiplayer: This is a brand new feature in R&C. I have not played online (no network adapter) but offline multiplayer was a blast! Up to 4 players can compete in Seige (my favorite), Capture the Flag, and Deathmatch. You go teams on all of them or free-for-all on Deathmatch. There are plenty of multiplayer-exclusive stages and weapons. Overall, this a an amazing game. I admit... blood would be nice... but if you can deal with fantasy violence, then you should definitely look into this.
