Inside Half-Life Opposing Force is a short GameSpot feature that offers eight new screenshots of Gearbox Software's upcoming add-on for Valve's "game-of-the-year" shooter, Half-Life. Thanks Ant. Here's a bit from the short write-up that describes the add-on's new weapons, as well as plans to add more all-star level designers:

The add-on features seven new weapons, including a new.357 Desert Eagle handgun. New characters will include a security guard nicknamed Otis, a new scientist model, and a drill sergeant.

And on the ultimate opposition spectrum, the game will also include one new race of aliens - the bipedal pitdrones. Opposing Force designer Randall Pitchford has said that Opposing Force will include much of what made Half-Life one of last year's best, such as a number of scripted events. Industry veteran Levelord has been officially announced as one of the designers of the game's multiplayer maps, and more all-star level designers are being assembled. Other well-known level designers who will be participating are due to be announced in the next week or two.
