Legacy is one of the most ambitious campaigns made for UT99, especially considering when it was made and that the majority of the project was done by one person, EZKeel. He is a mapper that made many levels for Unreal, UT99 and even UT2003 (I remember a Doctor Who themed DM map for UT2003 that was made by EZKeel, awesome

). Legacy is the third chapter of the Xerania trilogy and this is definitely the biggest and most ambitious one, with new cinematics, weapons, music, items, enemies and even a fully functional HUB system (something that the original Unreal tried to do

). This campaign is very flawed, probably the biggest issue is how unpolished the whole experience feels, the new weapons are a hit and miss (some are very unreliable while others are too OP), the new enemies aren't as deadly or smart as the originals and the levels, while they have some pretty cool concepts, they have some odd level design decisions which can annoy players. The story is very simple but there are plenty of messages to expand on the lore of the story, however a big issue that everyone brings up is the way the story handles religious themes, which is done very poorly. The ultimate irony is that EZKeel was a very religious person when he made all his SP content, but he quitted that religion in the future, so if he ever replays Legacy, he will feel the same way that most players feel when encountering those religious references in his work, oops
Cat and Mouse is the first playable map of Legacy, there is an intro cutscene before that sets the story pretty well. I like that intro however I'm always a little worried because at the end of the cutscene you can die unexpectedly because of rocks

. Cat and Mouse is a huge departure if you have played custom SP maps for Unreal/UT, because this is basically a puzzle map, you have to kill an enemy by using a crusher, get weapons and then escape, sounds pretty simple but the problem is that the first time you play this map you will be caught off guard by the unorthodox way of dealing with the first enemy, after that the map becomes a regular SP map where you kill enemies with weapons and find a way to escape. The level has decent level geometry, sure it doesn't compare to other maps that were being made at the time like the levels from ONP or Xidia but it looks good enough so you can enjoy the adventure, EZKeel has truly evolved as a mapper especially when you see the original Xerania where the terrain was made with cones

. The lighting of the map is decent as well, there are some good uses of the fan lights and this map (just like the rest) use plenty of fog, however this map doesn't use Ambient Lighting so dark areas look extremely dark, which can cause issues like players getting stuck like in the area where you activate the missiles to kill the Titans.
Sound design is a highlight of the map, this level really benefits from new computer voice lines provided by EZKeel's wife (she appears everywhere in those portraits) and sounds are used very effectively for all scripted sequences and movers. Music is good as well, the map uses Crater from Unreal and it fits the map very well, that song works so well in maps where everything is empty with a sense of dread and mystery as to what is actually happening. The map also uses a new custom song that was made by EZKeel himself, out of all the custom tracks that he did in Legacy this is my favorite, shame that it's only used in this map. There's many translator messages to explore the story of the campaign, maybe a little too many for my taste but that's just a nitpick. One cool detail of this map is that it uses Warp Zones to create the illusion of cameras all over the facility, I would have added an extra layer to the Warp Zone to create a video camera look by adding a texture to add visual glitches. Decorations are used very well, the suit from the ISV-Kran appears everywhere, this map also uses some decorations from UT like the pipes and lightboxes.
Issues I found :
-An issue of Legacy in general is that OldSkool doesn't replace the carcasses properly, so this campaign won't have permanent carcasses and chunks.
-Another general issue of Legacy is that there isn't a dispersion pistol equivalent (until much later in the campaign), so if you aren't careful you will run out of ammo and you will have no way to fight back.
-In the first room you have to touch the door of the vent so it falls to the floor, however if you are very unlucky you can get stuck inside that door.
-Also in the apartments you will see a vent door on the roof, this door causes a HOM effect because EZKeel used a solid brush instead of a semi-solid, what was he smoking.....
-Some of the apartments have a window to the skybox, which geometrically doesn't make any sense if you pay attention at the level.
-This map has plenty of places that either kill you instantly or hurt you severely, a little too brutal for the first map of the campaign.
-The first Brute is suppose to die by the crusher, however the crusher deals a small amount of damage, this means that if you are playing with mutators or the 227 new difficulties, the brute might survive the crusher, but that Brute must have an insane amount of health.
-Similar to the previous issue, the Titans might survive the Redeemer explosions, this has happened to me before but it happens extremely rarely.
-There are some texture alignment issues with cylinder brushes like the tube you use in the slime area, however I don't blame EZKeel for this since the original UT99 editor doesn't have an option to align cylinder textures. Also the texture alignment in the terrain section is very poor, some of the textures look very ugly because of the way they are scaled.
-The level isn't fully pathnoded, also the connections in the Brute-Crusher sections are very poor, which explains why the Brute has a hard time following you to the trap.
-This map has AlarmPoints and PatrolPoints but they are used very poorly.
-There are two Tree9 decorations in this map, this decoration is invisible because it doesn't have a mesh attach to it. This causes collision issues near the trees in the Brute-Crusher section.
-After killing the first Brute, the computer message gets cut off by the change of music, this only happens if you are using an old version of UT with the Galaxy audio driver, which was the standard when Legacy was released.
-The good old Female corpse texture issue appears in this level.
-The zones of this map are a mess, there are zones with more than one ZoneInfo, zones with no ZoneInfos, the final water area has FOUR water zones

and there are plenty of other zones caused by those poorly used solid brushes on the rooftop of the apartments.
-If you use the Frag Cannon on the area where the brutes appear at the end of the map, you can easily go out of bounds.
-The map ends with a cutscene, however the music doesn't work very well depending on the audio driver you are using, the song plays with the wrong tempo.
