First and foremost, know that Serious Sam 3 will keep all of the original items that made the game what it is. But it is a new iteration, so it also brings on a few more features. If you look below you will see what Croteam wanted to mix into the good old things. New things like enemies and melee attacks, big surprise. There is a nice 16 player co-op listed though, so that should make things a little more interesting. Here's the highlighted list sent on over.

• Frantic Arcade-Style Action – The calling card of the Serious Sam series, hold down the trigger and lay waste to a never-ending onslaught of attackers or face being overrun by Mental's savage beasts. No cover systems, no camping – it's just you and them. All of them.
• Mental's Fearsome Legions – A new battalion of unforgettable minions including the rumbling Scrapjack and towering Khnum join the legendary Headless Kamikaze, Gnaar and Sirian Werebull. Your days of mowing down zombie Nazi space pirates are over.
• Serious Melee Attacks – When an enemy slips by your wall of lead and pain, use one of the all-new innovative melee moves to drop an enemy right where they stand in the most violent way possible.
• Pure Multiplayer Mayhem – Play through the full campaign mode with up to 16 players or drop the gauntlet and let the heavy ordinance fly in versus modes like Deathmatch and Beast Hunt. This is the next level of Serious Sam multiplayer and all hell is about to break loose.

Now that we've gone through the important stuff, here are a few mindless screen shots for those of you out there that might be into that kind of thing. As usual with promotional shots, they look amazing but of course should not define how good the game is going to be.
