Unreal Tournament/Capture the Flag

Capture the Flag involves charging into the enemy base, grabbing their flag and returning to your base. To score, you not only have to grab the flag, but you also need to ensure that your flag doesn't get taken.

In the campaign, this gametype is known for deadlocks, especially on the later missions on a high difficulty.

A Flak cannon is found underwater, and it's closer to the red base.

The flag room is not a good location for long term defense; there are no health kits, and approaching enemies can wear you down. As such, you'll have to enter the central area to get the armor and health, as well as a few more powerful weapons.

If the enemy gets your flag, you can ambush the enemy, either from their access ramp, or from the door above your base. Most likely, they've been weakened by any skirmish they needed to reach the flag room.

Your best route to the enemy flag involves collecting both the armor under your ramp, and the thigh pads under the blue base's access ramp. This allows you to take more damage after doing a flag run, possibly enough to allow you to return to your base. The route back is debatable, but you generally want to return home as quickly as possible.

The translocator is useful in going to surprise defence locations, as well as grabbing the rocket launcher before the enemy.
