Anyone heard of the game Abuse?

I wouldn't say it was like Doom at all, but it was definitely a fun game.

Also had native Linux support from the outset, if I remember correctly.

Yeah, it was a pretty sweet run and gun in the mid 90s. Its best feature was mouse-aim since it wasn’t a console game.

I remember people saying that it was like Doom back in the day but I think that came from the fact that it was made by some ex id developers and that Doom/Quake, at the time, were really stand-out in that they supported the mouse (I swear it was only adventure games that were really making use of the mouse).

Shooting was a keyboard thing. And yeah, Doom was widely played on keyboard, it was designed for a mouse to be used too (said so in the manual).

Another thing is the game has health packs, ammo, weapon switching, etc which was very “Doom” but today you’d just see them as standard aspects of any shooter.

There’s a reason, for a long time before we called them First/Third Person Shooters, we called them “Doom-likes”.

It was pretty cool. Dimly lit side scroller/shooter. Worked with mouse aim which was weird for the time.

Also aliens (ants?) with rocket launchers

I recently completed a playthrough of Abuse. I remember it from my childhood as insanely hard, but actually I found it quite enjoyable.

Good parts: soundtrack, interesting puzzles, lots of save points so pick it up/put it down when needed, some of the weapons are really cool, ran perfectly on dosbox, artwork was nice.

Bad parts: no storyline, gameplay became a bit formulaic, end boss was disappointing, a couple of really boring parts looking for a switch or hidden door.

Nope, never heard of it.

I played it a bit in like 2014 or 2013 when my main computer was a raspberry pi. It was pretty okay but I never finished it

Yeah, on DOS I think. I remember the graphics being pretty smooth for the time. I couldn't really say it made me feel like Doom in 2D, but maybe I never thought about it that way. My memory is a bit fuzzy but I think it felt a lot slower. I think my install was shareware - I probably never played it through to the end because of this. edit: the linked article confirms DOS and shareware.

It was really cool. I remember it being quite fast paced action. Either it had a good soundtrack or just good sounds of enemies, weapons, don't remember exactly.
