2K Games today confirmed that Serious Sam 2 will come with co-op multiplayer, mentioning that on the PC 16 players can play through the game via LAN or online, while the Xbox version allows 4 people to play co-op using Xbox Live or system link. Check out some new screenshots here.

Serious Sam II features more than 40 levels spread across seven different worlds, each with entirely different environments. Gamers will wield nearly 20 different weapons and ride in 15 different vehicles battling against hundreds of enemies, some of which are minute, while others dwarf the player entirely. All of the same gameplay content is available in the multiplayer portion of the game, with minor additions to the maps to make the game more enjoyable for multiple players.
