When setting up a server you can see pictures of each level and of each computer player you create. In some ways the interface was frustrating. You couldn't double-click on things to select them. We appreciated the visualization but felt the interface could've been refined more. The Weapons and Pace Start playing and you'll immediately see the style of gameplay that Quake 3 promotes.
Characters run fast.
Weapons switching is fast. Weapons respawn fast. The pace is one of blinding speed. Lots of jump-pads and open areas contribute to the fast pace. You'll notice that ladders and lifts are absent from the game.
