It's easy to remove it. Just make sure you back up your map files before you install the mod. When you are done with the mod, just copy and paste your backed up map files into your map folder and overwrite the modded ones. Real simple.
As far as updates go, I haven't worked much on the mod lately in anticipation of the HEK comming out. That's when my mod will really take off. Just have a look at a few of the things I already have here waiting to be injected with the HEK (super special thanks to the Model God, Mrs. DoubleFire for these):
Those are renders of the Halo 2 human turret seen here:
That Battle Rifle model is currently being textured as we speak, and according to Mrs. DoubleFire, so far, it's shaping up to look exactly like this:
'HOG' billboard, seen in the E3 video:
That last pic you see there is an early render of the New Mombasa map, currently under construction, which will go hand-in-hand with my mod. I also have many other things in store which I do not have any rendered screenshots of including an accurate SMG, an ATV, a Brute Grenade Launcher, Covie Sniper Rifle and many other things which also include a Shadow, accurate Plasma Sword, accuartely modelled Gauss Gun, remodeled Warthogs, and so much more, way too much to list. You guys should really expect one kick ass mod once the HEK is launched.
Special thanks to Mrs. DoubleFire, SupremeTaco and Dr. Lime for the awesome models that are waiting to be shot into the game when the HEK hits, and also for a few of the ones temporarily being used in the game right now!
This will be much more than a mod. It will be a full-blown game. A completely diffrent application from Halo PC, including completely diffrent UI menus, music, SP missions and all. You are going to be able to compare this to the Half-Life and Counter Strike deal. Halo PC= Half Life, Halo 2 mod= Counter Strike. After the HEK, this will no longer be addressed as Halo 2 Mod, but actually Halo 2 PC instead, due to the fact that I am confident this will be the best and most accurate Halo 2 mod availble, plus the fact that it will be treated as a completely diffrent game.
Also, from the rumors, one can judge that Halo 2 will never hit the PC, so this will be as good as it gets, unfortunately
Of course, we must wait for Microsoft to get off their lazy asses and get that damn HEK out.
