As promised earlier (story) The Adrenaline Vault's Descent III Mercenary Interview is now online, getting the dope on this upcoming add-on for Outrage Entertainment's Descent III straight from project leader Christopher Pfeiffer. Here is a bit from the proceedings that gives a feel for what's afoot here:

Will there be any additional weapons, enemies or multiplayer options added?

There will be a new ship for the single-player campaign. The ship is the Mercenary's Black Pyro. It offers new weapon loadouts and has unique physics. The Black Pyro will also be available in multiplayer games. As for robots and enemies, we have around 10 or so new ones. Each level has at least one new and unique robot that has been tailored for it. The new robots have greatly enhanced AI and further our goal of having highly characteristic life forms for the players to battle against.

As for multiplayer, the new B-side multiplayer levels offer gamers a new perspective on online gaming. As an example, one of the B-side levels is actually a pinball table. The multiplayer mayhem is exceptionally fun within the confines of this completely twisted level. The other B-side level themes are being kept secret for the release. These levels are refreshing and very fun to play.
