#OpenXCOM
If you’re on a platform where you can run Steam and programs via Proton, that’s how I do it; just add the openXcom exe as a non steam game, set compatibility to proton experimental, and it works great 😊

I wish I could get openXcom working on linux, I wish they would put a flatpak out :(

OpenXCom has everything fixed. Turns out there were a LOT of things to fix, too. The old source code was a nest of bugs.

They have since apologized, cleaned up their act (mostly) and returned to the OpenXCom forums.

But it's still a pretty huge red flag that they still run a community chat server on decentralized chat-service Matrix for stuff too 'spicy' for Discord. If your community needs one of those...

Probably the biggest OpenXCom mod is X-Piratez, which is also a bit too cheesecake-flavored to be hosted on Mod.io

Worth mentioning that the mod was persona non grata on the OpenXCom boards for a while because its Discord community was so hideously toxic many got banned from Discord *for life*.
X-Piratez mod for OpenXcom
The year is 2601. The Earth has been long conquered by aliens. You run a gang of female mutant pirates. Rob aliens and their human proxies for fun, profit and power. Features: - Fight nazis with chain...

You can find most of the mods here:

mod.io/g/openxcom

If you want something Vanilla+, the Final Mod Pack is great. If you want a massive expansion on everything, conceptually, The X-Com Files is what you want. And 40k: Rosigma is an ever-expanding Warhammer total conversion featuring EVERYTHING.
OpenXcom Mods - mod.io
Mods can change or add new content like weapons, aliens, maps, missions, crafts, base facilities, etc. They are packed into folders and can be toggled on and off ingame.

Seconding this. The OG X-Com has seen an ENORMOUS modding renaissance in the past few years thanks to the OpenXCom engine. The best way to play it vanilla, as it fixes a ton of bugs and improves the UI.

Some of the biggest mods dwarf the original game by a factor of ten times the content or more.
If you’ve ever been curious about the origins of X-Com, or the mods I post about from time to time, it’s on an incredible sale right now! For $1.50 you will get hundreds of hours of one of the best tactical strategy games ever made 😊

Also yeah mind control makes it too easy 😭

Between Doom, OpenXcom, and this, that era of DOS gaming was truly something special.

Im watching an openxcom handmode let's play and so far it's been very funny how every terror mission has required immediate mission aborts. The last one has two cyber disks and a crysilid immediately visible from the starting area.

Hmmm. Do I get the entire classic X-COM collection to play with OpenXCOM or do I finish the XCOM 2 collection and play that. Hmm.

Se quiserem, Instalem o OpenXcom pra bugfixes, HD nativo, algumas mudanças de design do jogo e uma fã-traducao pra PT-BR.

I think I'm going to stream on #Twitch tonight (in ~5 hours). Probably #OpenXcom, #DwarfFortress, or #HOI4 #Kaiserreich. Let me know what you think!

Rosigma 3.0A is now up, same link as for 3.0 above.

A bunch of fixes, and an new strategy: the Assassins.

Featuring the Sisters Represalia I had in the drawer for a couple of years. SpecOps for the Adeptas Ordo Dialogus.

From a glance there's at least one openxcom for windows xp that works as of 2024 woo
September 12, 2025 at 2:34 PM
openXCOM also lets you play around with mods, including an X-Files inspired total conversion where you start out as two agents and eventually become a shadow organization and X-Piratez, which seems to basically be eurojank xcom by one singular pervert with a vision incomprehensible to humanity
September 12, 2025 at 2:34 PM
openXCOM lets you play the original UFO Defense with a bunch of bugfixes you can toggle on and off, unsure if it's compatible with older hardware but that's my first recommendation point. terror from the deep is basically a kaizo romhack and apocalypse is Weird
September 12, 2025 at 2:32 PM
openXcom does a real good job of adding QoL features while keeping the both games hard as nails though! and thats great in the meantime.

Early draft of the new Alien City mission!

(apparently the answer is YES BTW, OpenXcom has multiples) bsky.app/profile/chao...
"X-COM Terror from the Deep Refreshed and Relaxed" by LordKane is the latest one and it's pretty comprehensive
