DsS from TSC has found a glitch that allows you to walk through any sufficiently thin wall and fall though any floor (nothing new there lolol), and another glitch that allows you to use the uppercut as a superjump to grab poles and such things. His summary from YouTube: Shamar night in 79 seconds. There's all kinds of ordinarily inaccessible areas that can be romped around, but the most notable is in Adabat: you can reach the area past the goal ring that's normally barred off by a solid gate, and within lies an unused device that changes the water level and a tree that can be knocked down to walk across. If you can manage the wallwalking glitch, you can get to it by going through the barred door on the right side of the Adabat ghost mission, after which the ordinary goal ring area isn't barred. He's putting up a video, but apparently having some problems with his DVD recorder <_< edit: not directly related to the above glitches, but another hidden area in Shamar, from Paraxade of TSC 8) edit2: DsS has put the video up for the Adabat hidden area. It's primarily a round chamber with platforms that rise with the water level as you reach each new platform and turn the switch, similar to Lost Temple or various Zelda puzzles, with the level's actual original goal ring chamber at the end - since he's actually in the ghost mission, activating the ring results in a failure message. The reason they cut it is pretty obvious once you watch it: while the platforms and the kill plane rise, the actual water graphics don't. My guess would be that it got left on the cutting room floor when time was short. It's a shame, as the concept is much more interesting than the rest of the level and the ring chamber is quite a bit more impressive than how they ended up leaving it in front of a barred door. Given that the engine capabilities for handling the area don't appear to have been implemented, I'd say that's fairly solid evidence against these hidden areas simply being reserved for DLC.
