Ivory Tower H3 is a remake of the default map 'Ivory Tower' from Halo 2.
Since Sandbox gives people a lot of options to built maps, favorite maps of Halo:CE and Halo 2 have been remade by forgers and got downloaded by interested players, among them is me.
But I also wanted to play on 'Ivory Tower' but could not find a remake on Sandbox. So, I thought I try to built it myself.
It took quite some time and I needed to visit the original map alot to get the remake close to it in layout, size, details etc.
I used the whole budget and since I just used the default respawns, necessary weapons and the objective items from Sandbox there's also no more item possible to be placed.
All the original weapons, grenades and the OS got placed and every gametype is supported.
Power weapons respawn within 2-3 min, most of the other weapons at 30s.
The maximum of BR's and Carbine's on the map is set to 6.
Recommended gametypes are Team Slayer, One Flag, One Bomb (two bomb plant spots).

Issues?
1.The glass wall near OS is missing, but building a structure out of shielddoors and solids is not possible without budget.
2.Some airlifts are missing, but using grav lifts would be to expensive so that the usage of them would reduce the map in other details.
3.Sword is not underground enough? It is a compromise again due to budget and object limits.
4.The roof of the tower got built with golf items, because they cover more area than other items and they are cheap. The main idea was to get the right feeling within the tower passages and let people not escape the map with normal or grenade jumps. See the description on the bungie.net file for the logical use of those items. ;)
(Also, I wanted to place an antenna for the tree in front of the tower but due to the fact that a bomb explosion underneath (on the gametype Assault) makes the antenna jump, the antenna hits those golf gras items and they then try to pull it into the wholes (such as usually golf balls). That is why I placed a solid item there.
Normally the tree does not touch the tower, but in the remake the item does: with that I prevent people from exiting the map from this very item.

Enough talk, have pics (from haloscreenshots.net):

If you 'stand still' while rising with the lift you get up easily, whilst pressing forward may let you hit the wall. (behind the tower)

It is not that cramped as it looks here. (the 'park')

One of the tactical jumps thought of to be possible.

The Sword passages. Not as underground as people might be used to, but at least implemented..
