Transmit is a smaller map I'm putting together for the asymmetrical map contest. Its layout is similar to Mountain Lab, with three control points open to BLU capture, and only one unlocked at a time. If BLU captures all three control points, they win, but RED wins if they hold at least one point at the end of the round.
The map is set in a communications center held by RED, with a large antenna to relay messages to other key strongholds. The base itself lies in the middle of a large, highlands forest surrounded by mountains.
The design goal of the map is to provide the quick, snappy rounds of KOTH while still allowing the opportunity to set up a firm defense. Hopefully, this will cater to both offensive and defensive-minded players who don't want to commit to the long round times of a traditional A/D map.
Here are some screenshots from A2:
