In its basic terms, Demolition is a variation on Capture and Hold, except you try to capture and blow up specific points on the map. The two new maps have different ways of handling those objectives. The Colmar map has two points for each team to destroy (they are made up to look like APCs, artillary guns and other military weapons) and of course each team has to defend the points that the other is trying to detonate. The Colmar map has a bridge in between the two team locations that's filled with explosives (which would be a pretty dangerous place to be normally but that's another story) that team member can use to pick up a TNT load. Players then go to the points to blow up, hit the "E" key to place the TNT on the specific point and wait for the explosion

The two new levels in the Demolition mode were quite impressive. The Colmar map is a winter themed map set at night in a European village with a frozen creek underneath the bridge that holds all that TNT. The Jagd map is set in daylight in a bombed out village that has a lot of multiple levels and some interesting features like ramps in certain locations that are one way; you can run and jump off the ramps but they are so high you can't move back once that's done.
