Haydee

Haydee is an action-adventure game developed and published by Haydee Interactive, and was released on September 26, 2016.

Why It Rocks

 * 1) Just the mere fact that the game combines all of the five aftermentioned genres and combines them all into one, is an impressive feat to accomplish, especially since it's all in 3D.
 * 2) An extremely challenging difficulty that always keeps you on guard with whatever could come next.
 * 3) The Survival Horror elements are really well-executed, with the complex you're trapped in having a creepy and oppressive atmosphere akin to the first Portal game, and the enemies sometimes ambushing you in a jumpscare manner. The Black Zone is this especially since it's almost completely pitch-plack, forcing you to use your Visor (which has such an incredibly limited view distance to the point where you can't even see what could come after you), the ambushes are most apparent in this zone, and the music is significantly creepier here than anywhere else.
 * 4) The graphics are pretty nice to look at considering the game was made with no budget.
 * 5) Over 160 rooms to explore, plus with the fact that the artificial complex itself is massive.
 * 6) Each zone is differently color-coded which alludes to its theme. The White Zone is the tutorial, the Green Zone is platforming-based, the Red Zone has a lot of pipes, the Yellow Zone is flooded with poisonous gas, the Blue Zone is underwater, and the Black Zone is pitch-black and swarmed with enemies.
 * 7) It has plenty of puzzle-solving in every zone, though the Green Zone is the one that focuses the most on this.
 * 8) The game is pretty well optimized, allowing low-spec PCs to run the game at a decent (or higher) framerate. This also extends to the sequel.
 * 9) Tons of modding capabilities for a game that wasn't made with modding in mind.
 * 10) Plenty of references and inspirations from other video games to be found here.
 * 11) The game has a huge potential for speedrunners thanks to how fast-paced the game is (outside of platforming), there's even an achievement for beating the game in less than 60 minutes.

Bad Qualities

 * 1) The controls are pretty clunky and barely feel tight at all. It's even worse since some of the controls (like swimming) aren't really explained to you unless you go through the settings and look for the controls.
 * 2) For some reason, the camera is positioned in such a way; that it always focuses on Haydee instead of the environment around her, making it not only a bit of a hassle to explore the already claustrophobic facility, but also a case of borderline fake difficulty since she could obscure some enemies coming your way.
 * 3) The game, in general, doesn't give any kind of hints or any kind of clue on what you're supposed to be doing in the game.
 * 4) The endings aren't really worth it all because not only are they very underwhelming, they are also all pretty much downer endings, making all of your progress in the game completely meaningless.
 * 5) While the difficulty is kinda fair, it can pull some nasty and unfair tricks at some parts of the game.
 * 6) The platforming can range from tedious and boring to genuinely bad.
 * 7) Changing the windows and resolution is way more complicated than it needs to be. Plus, when you boot the game up again, the resolution resets.

Trivia

 * At one point, it was planned for there to be a shotgun in the game's arsenal to be used against enemies but was cut from the final release. The shotgun would have done up to 200 damage but has randomized spread. It was scrapped during development, however, the animations and some of its data. Such as bullet attributes and spread were leftover in the files of the final game's release.
 * Originally the game's protagonist was going to be a human woman named Eva with similar clothing to Haydee in the final release. She was cut due to the developer's having technical difficulty regarding her outfit. Eva also had a nude model since at one point there was going to be an area that would require players to remove all clothing, but this idea was scrapped due to the area forcing players to forgo the Armored Vest which made the game harder than it would be. Evidence of the scrapped nude Eva models can be found with the uncensored ammo, medkits, and keycard items. Eva's original character design can also be seen on the game's Steam Workshop page, and a mod that recreates Eva's original character design was later made available by the developer.
 * There was going to be a third enemy type called Ranger, which fought players with firearms instead of using melee attacks, but the enemy was scrapped early in development as the developers felt these enemies were not enjoyable to fight against.
