A2b a2b is an abstract train game where you guide trains to their destination without letting them collide with each other. Each game is played on a set of tracks on which trains run at regular intervals. You pick a train and accelerate, brake, or stop as necessary to safely guide it to its destination. Since trains are continously being launched, more than 1 train will want to use the same section of a track, potentially leading to a collision. You must resolve this by making a train wait while you rush another train. As a last resort, you can send a train back to its base.

Rogues have no teammates (not even other rogues), so they cannot shoot teammates and they do not have a team score. There are two main styles of play: capture-the-flag and free-for-all. In capture-the-flag, each team (except rogues) has a team base and a team flag. The object is to capture an enemy team's flag by bringing it to your team's base.

The object is simply to get as high a score as possible.
