Serious Sam 2 will feature the mass hoardes of enemies that Serious Sam: The First Encounter and Serious Sam: The Second Encounter presented, with an upgraded engine. In addition to graphical upgrades, the physics engine powering Serious Engine 2 is highly advanced and robust, and nearly everything in the game will be destructable. Each destruction will be unique, as the physics engine will handle things as realistically as possible. Multiplayer: Co-op is confirmed in Serious Sam 2, and will support up to 16 players. Other multiplayer modes may be available, but not much is known at this time. Many of the skins from the original games will appear again in Serious Sam 2 multiplayer.
