Gold Rush is a different map from most of the other maps because it has very long routes from one point to another. However these routes do meet between the power weapons with Boomshot and Torque Bow Spawn having a window of opportunity available.
The level is a big test for two teams who face each other, and often the team that are able to stick together and make the most of the upstairs area that over sees the lower areas power weapon will ultimately have a better control over the map.
Because there is little opportunity to get behind enemies, it makes sense to keep your unit tight together and play the game in a more linear approach to other levels such as Gridlock, which have plenty of flanking opportunities.
The other weapons featured on this level are Grenades, and Boltok Pistol.
