As promised, Croteam and 2K Games have released a new demo for Serious Sam II, which incorporates all the changes from the recently released patch. It also contains a new level from the full game (“Greendale”) as well as the level from the initial demo, both of which can be played single player or in on-line co-op. The demo supports up to sixteen players in on-line co-op, just like the full game (it’s not limited to four like the previous demo).
