I don't do posts like this often,but when I do I like to cover them in great detail. I have played over 80 FPS Games, and many of them have turned out to be ones i can easily beat, but these top 10 ones are insanely hard in many ways. This is a post ranking the top hardest 10 FPS games I have played.
Before I begin, I would like to say a few things. These were ranked by their easiest skill only. I didn't do this on the hardest skill, because I never really play on the hardest skill unless I want an extreme challenge, and to me ranking them on their hardest skill is not a good measuring stick compared to doing it on easy, because I find that a lot of FPS games have brutally difficult easy modes these days. And back in 1998 or so it started to really get notice able with the release of Half Life that easy mode would not be easy anymore.
10: Quake 1
This game is NOT easy and you find that out really early in the game if you dare to play it on The enemies do a lot more damage than in doom, are far harder, weapons are noticeably weaker than in doom, health is less common and ammo is rarer and you can't pick up as much. That sums it up. Is it fair, sure, but it's a lot harder than games before it.
9: Doom 2
Why is doom 2 on this list. Normally it should not be anywhere near a list of hardest FPS Games, but thanks to it's addon levels, which lean forward rediculous SLAUGHTERMAP gameplay, you get this on the list for it's custom maps only. Stuff like Hell Revealed, Alien Vendetta, Sunder, etc is so hard that it makes the original game look 1/50's as hard. Massive hordes of medium strength miniboss monsters, huge numbers of revenants, limited health, archviles in big numbers, sometimes even in hordes, cyberdemons being used a lot per level, etc, these kinds of maps push this game beyond Quske 1 in difficulty, but not by much, because even they pale in comparison to the heavy hitters. What makes this only 9 is mods though, with the right mods these maps are far easier, so it is still only slightly harder than quake 1.
8: Hexen
This game is mean. It has a mean streak. Mean traps everywhere, some of them death traps, bottomless pits, crushers that are almost impossible to avoid, extremely confusing puzzles, etc. This game is actually a lot harder than the Doom Games. Heretic is not that hard but hexen sure is!
7: Descent / Descent 2.
This game is fucking hard. Enemies are very mean, the level design is mazey as hell and gigantic, and it has this crazy "you must blow up the level and escape before the countdown runs out" mechanic. Combine that with hard enemies, limited health/shield, limited lives, and such, and you get one hard game.
Descent 2 is even harder, with nasty enemies that can navigate the mines better than you can and some steal your weapons! It is even worse when you factor in the thief bots in this game.
Weirdly, Descent III is nowhere as hard as the first 2. It is strange, as the enemies are easier to deal with, the thiefs are nerfed a lot and the end game is the only really hard part.
6: Hexen 2
This game is actually FAR harder than hexen 1. Why? Harder enemies and weaker weapons might be what you think would make this game harder, but actually the puzzles are the main reason. First 2 hubs are no harder than the first 2 hubs of Hexen 1, then it gets crazy with over the top puzzles like the tic-tac-toe puzzle and similar in hub 3. Some of these puzzles require you to find hints in other levels that are very hard to find out, or are hidden. Some don't even have a hint! Or a good one. Combine that with hard combat and you have a frustrating experience.
5: Jedi Outcast
This sequel to Jedi Knight is brutally hard. What makes it hard. Insanely weak weapons, plus brutally difficult snipers that have no signs to tell you where they are, stealth missions, unfair gameplay, you name it. It starts bearable, but as soon as you reach nar shaddaa it gets insanely hard instantly fast. The damn snipers in that mission are a bitch and your sniping weapon sucks and unzooms when you try to dodge them. And that is the only gun that works well on them to make it worse. And to make it worse, they keep on coming in bespin too, and by the time yo.u reach the cairn they are gone, only to be replaced with insanely hard force power puzzles and stealth missions. This one is brutal and unless you like extreme difficulty, avoid it.
4: Serious Sam
Serious Sam is the one exception to the rule on this list. All other high-tier games on this list have insanely hard easy skills. But Serious Sam is the one with a pathetically hard super easy skill, but as soon as you crank it up to easy it becomes insanely hard. So if you want to beat it you need to be able to get lucky. It relies on horde combat, tons of enemies that do lots of damage in battle arenas, mean placement of enemies, enemies spawning behind you, sniping you, etc to provide insanely hard gameplay. This one is often called brutally hard, and for good reason
3: Half Life
This game actually is the weirdest one on this list due to how easy the beginning is. The beginning before we've got hostiles is easy as pie and the aliens pose almost no threat, but as soon as the grunts show up it becomes brutally hard. The grunts are so fucking difficult it's not funny, they are intelligent but that's not what makes them hard, it's how much damage they do! Their damage is insanely unbalanced for easy. The grunts go away for one chapter, but as soon as they come back in powerup it gets insanely hard, and then there are the two grunt fest chapters which are insane (On a Rail and Surface tension). Good luck beating this game on easy, I did it but I got lucky.
2: Deus Ex
This game is marketed as a stealth game, and if you play it that way, it might be easy, but if you try to run and gun through it, it's insanely hard. I found a way to mostly do it and beat it that way, but it all depends on how much skill points you put into gun skills. And it gets brutally hard later on. Around Paris it is so hard that you need to be stealthy or lucky to beat it Don't get me started with the save tiffany mission, that is brutally hard as well.
1: STALKER : Shadow of Chernobyl
The hardest FPS I've ever played by far. This game makes Half-life and Deus Ex look easy. Mean traps and anomalies, insanely hard soldiers, limited health, guns that are a bitch and don't fire straight, enemies that can head shot kill you from a distance, etc, this thing is downright mean. I had to reduce damage to the player to even beat it fairly.....
