TPU now includes a new, experimental version of the Midway map. It replaces the previous version, at least for now. Whether it stays in the rotation depends on whether people prefer it. So please let me know, one way or another.
The new version includes PT boats, BF109s and B-17s, along with a few other changes. Should make for a crazy new kind of fight.
UPDATE 2010Feb21: there were a few problems with the new Midway map, which I hope have now been fixed. Feedback welcome as always.
