haymaker, I made the cows for another mapper, but couldn't resist throwing them in behind some glass just for a laugh. There's a good chance that they'll get removed for the final release. L4D seems to have stolen a lot of players away from tf2 servers, but even so, it's still a great game to buy if you've got $20 to spare. The pipes, and a few other pros need to be tied to an info_ligting thingumy because they have their origins inside brushes atm.
Redwood, most of what you mentioned has been addressed in this build. More health and ammo can be found close to where angies will need it.
The thing about taking the flag to the battlements was how 2fort originally played in tfc, and I thought that people would 'get it' reasonably quick. That didn't seem to happen, so now you take the intel back to where your own is. The outside area was far too big before, which caused a lot of deathmatching, with not too many people managing to get to the enemy base. This meant the outside had to be completely remade to be a good deal smaller, and now looks just like the 3rd pic.

If I can come up with a suitable name, then I'll change it away from 'fishy', as there's nothing atm to connect the name to the theme.
