diablo 3 will play very similar to Diablo II, however Blizzard has chosen to completely redesign the game engine to incorporate physics. The game will now feature fully destructible environments that play into the game mechanics – allowing players to do things like bring down a wall to dispatch a large mass of enemies.
The new game engine supports 3D environments as well to allow interaction between the players and game enemies. Several game demos have shown enemies making use of the 3D environments, doing things like climbing up a wall in the background into the foreground.
Diablo 3 will be presented in a top-down or overhead view to compliment the previous games isometric viewpoints. It will also include online drop-in, drop-out cooperative multiplayer gameplay through Battle.net (Blizzard’s online game service).
