Valve have released a CTF version of Well, which i think is good because there a two many stalemates of CP well.

"Team Fortress 2 now has a brand new map. Now you can play two versions of Well: the existing control point map, Well (CP), or a new configuration, Well (CTF), which replaces control points with intel capture points within each base. Have fun out there...and watch your back."

I havn't played it yet... (tho I have wandered round).. there are a couple of slight map changes like a staircase down to the 'well' exit in the base....

Seems like a good idea to me, although Valve's quote of "Team Fortress 2 now has a brand new map..." should really be "Team Fortress 2 now has a re-shuffled old-map..."

"brand new map" LOL looks like a rush job to me. It's only just about ok, nothing special.
