STRAFE

A really good fast-paced rougelike if that's what you are looking for. Even after finishing it I find myself coming back to play it every now and then

If you look at my profile you can see I like a lot of roguelikes. Of all the ones I've picked up over the past few years, I feel that this is the most ignored little gem. It seems like its marketing and production difficulties doomed it to obscurity, combined with a bunch of people seeming to expect a wholly different game than the one they were making, which soured word-of-mouth spread.
But! I think Strafe is worth the time for anyone who reads "boomer shooter roguelike" and has their neurons start firing. Using the primary weapon as a replacement for the usual classes or characters of a roguelike is an inspired choice, and once you get the movement down (which will take some work!) it really does feel like playing a Quake or Unreal roguelike game, complete with insane circle-bunnyhopping through the levels at mach 1, slaughtering scores of monsters who explode in the most gory, satisfying way. The best way to understand how the game wants you to play is to look up the JumpZone secret video - that area expects you to understand all the silly little movement tricks that defined high-level arena shooter play in the late 90s. Once you see what you could do as a master, you can experiment and train through the normal levels until you feel like the God/ess of mobility, untouchable. It really starts to feel like *strafing* -- the way a fighter jet strafes a target, annihilating them as you pass by,
There's some strong influence from immersive sims like System Shock present in the game too - generating individual areas that require you to find the correct severed head to open a door, for example. Managing your health and ammo supplies versus speed (as you're rewarded for quick level clears) adds the same sort of edge as Risk of Rain's escalating difficulty.
Narratively, the game is very bare, but that forms part of its charm. Like Doom or Quake, the game is more about a tone and aesthetic than a story, and if you miss the gritty industrial grime of sci-fi settings like Unreal Tournament, this will be right up your alley. The soundtrack feels like a great throwback to the golden era of PC gaming soundtracks, powerful guitars and driving synths giving you a rhythm to your murder. I find myself waking up with a track in my head and feeling determined to get to the level that features it.
Finally, while its longevity is limited by the lack of mod support or community, there's an impressive amount of content in this little game, comparable to similar titles like RoR. The mutators act as the game's version of Artifacts, fundamentally altering the structure of the game in most cases (which can be good for achievement hunting). I personally prefer the balance of the new game+ mode (3 levels for 4 zones, rather than 2) but having both options available is aces. The arena mode is barebones but pretty fun if you want to just play some STRAFE combat without the struggle of finding your way through procedurally generated levels (and this mode has the most rogue*lite* elements, getting easier the longer you play -- the standard mode without mutators does not give you this mercy.)
Bottom line, I'm leaving this review because I think this game has a lot going for it, and I'm bummed every time I remember how little following it had and how mean-spirited and unforgiving the playerbase seems to have been towards the developers. (Calling a game 'abandoned' after three years of support is silly, guys. Games have to stop being updated eventually.) I'd recommend this to anyone who wants to feel like they're back in the 90s and figuring out the bizarre tricks of the idtech engine's momentum code while getting the constant little upgrades and resource management challenges that make roguelikes fun. I was hesitant to buy this game because of the lukewarm reviews, but once I got what it was going for, it all clicked into place. If any of this sounds fun to you, I encourage you to spend the 15 bucks.

Best jams out there with a super gory fest of randomized levels and crunchy guns.
Apart from Deadlink, none of the other Rougelite FPS games managed to do anything good.
STRAFE is one of those games that did.
Highly Recommended.

There are better rouge likes but idk this game fun (also the music is fire)

1996's finest product. Total addiction.
My rating: 10/10

To start off this is not a Boomer Shooter per say, it has some elements and is styled after 3D FPS games from the mid to late 90s but fundamentally this is a Rougelike.
I was very disapointed by that fact when i first played it, as seemingly were lots of others (it has to be said this game does a terrible job at marketing itself, it is nothing like what most of the marketing material makes it out to be which is partly why i am writing this review). Since then i have had more experience in both Rougelikes and Arena FPS, which is more of what this actually plays like. Seriously this obscure game has better movement mechanics than any AFPS i have ever played you are never told but once you figure out how to stack strafejumping, double jumps and acceleration you will be flying through levels.
The best way i can describe it as is a first person version of Enter the Gungeon but without the Bossfights and with the movement and verticality of Quake 3.
Sadly many things are not communicated well or at all and the only documentation online seems to be steam community guides (those are very good however and i would recommend looking at 1 or 2 to get the basics down). The corrosive blood of most enemies can be irritating at first but actually encourages you to learn the movement mechanics and can be painted over with other liquids so it pays to finish those enemies first to have their blood hurt their allies and then kill those to paint over the acid. The guns are fun and can further modify your playstyle but it can be frustrating if you don't know what the upgrades do and get handed one that you don't like with no method of changing it for 5 floors. Besides your primary weapon you can still pick up dsiposables in the levels though which all act differently and are based, in their function, on iconic guns from other shooters (you can even plasmaclimbe) and the Bolter from 40k.
Apart from that the game is brimming with style and personality (which granted you might not like but the vibe should be obvious from the store page and trailers) and is packed with secrets and even secret minigames and challenges. I have only encounterd one bug which was seriously annoying for that specific run but not game breaking or distracting and only occured once in what must have been over 200 runs.
There is also lost of stuff to unlock that transcendes individual runs and you can activate modifiers or let a run go on infinitly or choose wave mode if you just want to test your mettle against hordes of enemies.
If the main loop i described seems fun to you and you love Rougelikes and AFPS this is a must (though again i highly recommend looking at the user made guides to get started) if you are just casually intrested wait for a sale (and i can't say this enough look at the guides on the steam community page).
Edit: Oh yeah the jump map challenge (if you can even find it) is one of the hardest things i have ever powered through, took me over 3 hours (fuck plasmaclimbing) the first time for something the Devs could do in less than 15 minutes but i felt like i owned the world after beating it. If you can do it too, please post your time to the community page.
