Infernal Falls, the second map of EXU2 if you don't count the intro, this is the real first map of EXU2 where the game reveals what this campaign is all about : insanity

. EXU2 maps are all about pre-planning, being very careful where you go, trying to attract enemies so you can kill them one by one, using the flares and of course : saving the game every 5 minutes.
The map uses the original Nyleve Falls as the base, however the level was changed so much that it's almost unrecognizable, the textures, sounds, enemies and weapons are completely different, not to mention the lots of extra stuff that was added to add more details. The geometry from the original map was left intact for the most part, however new brushes were added like the cracks on the walls and the satellites in the background. By the way the satellites aren't meshes, they are brushes, amazing brush work and a lot of work for something that's just a background detail......, or are they?

. The texture choices are great, it's weird seeing the map with lighting turned off since the lighting makes the level look so different, the maps from EXU2 are a great example of how textures and lighting can be combined to do something breathtaking. Texture alignment is also amazing, thankfully the texture alignment of the original Nyleve Falls was already very solid, so this map didn't had to worry so much about fixing the issues from the original map.
The sound design is fantastic, EXU2 is a master on how to use sound effects in a map, plenty of Ambient Sounds combined with Dynamic Ambient Sound are used to create the unique atmosphere of this campaign. The music is also a highlight, the song is called Lost Technology by Cybernetika and it fits the map perfectly, where the atmosphere is all about you being thrown into a hellish environment with monsters from another dimension where all the odds are against you.
Also I want to mention the excellent use of special effects in this map, especially the skybox with the use of panels, projectiles and textures.
Gameplay is also great, this map is the first map of EXU2 where you have to learn how to play this campaign properly because if you don't, you won't survive long. The enemies of this map are very varied and they all require unique strategies to beat them, but thankfully you do have enough tools at your disposal to defeat them, especially the flares, they are your best friends, you have to use them only when you really need them and they are the best tool to clean an entire room that you haven't been yet, also the flares are very useful to deal with the toughest enemies in this map. The key to beating this map is taking your time, attract enemies to a corner so you can kill them one by one, using the purple crystals with the Piddledoper's primary fire (the EXU2 Automag) and using the flares sparingly, because you will need them in the next maps. Also you need to explore this map as much as possible, there are plenty of hidden pickups and flares. This map is very difficult and it requires a lot of trial and error, so save often, make sure the save system doesn't break, after all EXU2 is infamous for the save glitch.
Also in high difficulties be careful with those volcanos, they are not there just for show
And also be very careful with the Turbo Queens in higher difficulties, they are the worst.
Issues I found :
- The EXU2 maps have an actor called EXMapInfo which gives you some default inventory when you open the map from scratch, however all EXU2 maps have that turned off for some reason.
- EXU2 has a hint system for lower difficulties, however there's no hint system when it comes to using the purple crystals.
- There are no secrets at the top of the ship, there's something but it only appears in lower difficulties and it appears very rarely.
- The elevator that takes you to the bottom section is CrushWhenEncroached and it doesn't use EncroachDamage so it only affects you.
- There are many ammo pickups that don't appear in higher difficulties, which I think it's a problem since you need more ammo in those difficulties.
- At the section in the original NyLeve Falls where you fight the first Brute, the movers that take you to the bottom section are already opened in
Infernal Falls, however the movers use KeyNum 1 and the keyframe 0 is out of bounds for some reason.
- The last doors are ReturnWhenEncroached.
- The map uses a normal Tentacle carcass instead of using the EXU2 counterpart.
