Unless they totally suck.
You decide!
Overflow and Destructoid are being added to the rotation on Tempest 3 after a successful map test tonight with a bunch of pdsers (and the author of Overflow showed up as well).
We also tested horus and, while it is one of the most amazingly detailed maps I've seen for TF2... it's not quite ready gameplay wise for rotationing.
However, we all loved Destructoid and Overflow... So we're going to give those two a shot.
