One Flag Capture: g_gametype 5.

There are three flags in this gametype: The blue, red and white flag which is usually located in the middle of the map.

A team must take the white flag and bring it to the enemy's flag and prevent the enemy from taking the white flag to the teams own flag.

When a team makes a capture by touching the enemy flag while holding the white flag, the white flag will be instantly returned to the middle of the map ready to be taken again.

This is a gametype from Team Arena, thus you will not find it in most mods designed for Q3A.
