I grew up playing this game when it first game out. Absolutely loved it. The PC version will require a third-party patch to handle CPU issues. Other than that, it played great. Took about 5 hours. Hated paying the $20 for it, but for the nostalgia it was worth it :D

I feel like this game takes a lot of inspiration from other fpses coming out around the same time, like doom 3, FEAR, Half life 2 and so on.
The graphics look a lot like those from Doom 3, just with a slightly different art style.
The time manipulation abilities are interesting in theory, however you really just use pause and slow during gameplay.

I suppose the natural comparison would have to be FEAR here, which has bullet time like max payne but in first person. The thing about this though is that the AI in FEAR appear to be much more intelligent than the AI here. The gunplay in FEAR feels so good even if you never touch bullet time, whereas here you are more or less forced to use it as a crutch.
The gunplay and melee is very unsatisfying, as the enemies are bulletsponges and there is little in the way of satisfying sound design, the guns sound like pea shooters and there is little response from melee attacks.

Also for some reason it reminds me of Crysis 2, I think because it is so linear. Also it really doesn't reward exploration like every good fps should and the story is barely there. There's worse shooters out there for sure, I've even played and finished a few worse fps games although this doesn't really work in the same sense as rogue warrior because at least playing that is kinda funny.

There are a handful of puzzles drizzled throughout, clearly inspired by those found in half life 2 but with a twist! They suck! All you do is pause time and waltz through fire, electricity, or go from one side of a pendulum to the other.
You are better off playing one of the games that clearly inspired this, those being FEAR, Doom3, or Half Life 2.

Also seems like most people that like this, like it due to nostalgia. It fails at a lot of the things established very early for fps games like having secret rooms, stuff like unlockables, more than three guns at a time, or improving the tools you have ala fears time abilities and so on.
