Four screenshots and fly-through video from Valve's new Team Fortress 2 map Gold Rush can be seen on this here page.
Gold Rush forms part of an imminent, major update for the multiplayer shooter that's introducing unlockable weapons, initially for the Medic class. Full details on the new Medic weapons emerged yesterday.
The new map features a brand new gameplay mode. In the new mode, one team must escort a small mining cart through a series of Dustbowl-like map segments. The cart moves faster the more Blue players are near it, but stops entirely if even one Red player is in range. Blue have to escort the cart all the way to Red's headquarters within a certain time limit.
Valve's update will debut on PC, with Xbox 360 and PS3 versions sure to follow.
