I reccomend that X-com player is allowed to see what Alien player does, while Alien player is not allowed to see what x-com player does, unless x-com player allows it.

The map vision gets reset because one can guess where units by seeing which doors get open and where items are left on the ground.

For Alien player, clicking the Psi Button with Ctrl pressed, will select the Mind control action. Otherwise it will be a Panic atack. Aliens can also abort mission, while holding Ctrl, which results in every alien getting stunned.

Added 3 adjastable options, due teedback received.

1. Turns taken penalty, which can also be set to 0 (right click it to reduce the number) .

2. Fog of War : Clears map vision at the end of the turn of x-com and neutral side .

3. Hot Potato Grenades: Grenades are not allowed to be set to 0, they explode in the inventory and primed grenade indicator is only shown when grenades are held in the hands.

4. Drunken Blaster Laucnher: Sets drift accuracy modifier of guided missiles from 60% to 5%.

Avoid saving during non-xcom turn. I am thinking a way to fix the issue with that.


1. It is required that you have OpenXcom directory in "(My) Documents/OpenXcom", which contains original UFO/TFFD game. Any Open-xcom mods you want to play with should also be in OpenXcom/mods folder of that directory.

Optionally replace en-Us.yml file in your OpenXcom/common/Language folder

2. Unpack archive anywhere you want and launch.

You can play remotely with others via Steam link, Steam remote play(enable openGL filter) , or Parsec for example.

@ Evil_bl for my first x-com multiplayer expirience playing Ufo:The Two Sides. He is an Ukrainian Streamer. evil_bl
@rankin_chafer For multiple mutiplayer expiriences in UFO:The Two Sides. He is also from Ukraine.
@Finnik723Studio for teaching me how to work with open-xcom rulesets and c++. He is a developer X-com: From The Ashes, check his discord and support him if you like his work.
@BratGronflo for his determination to make multiplayer open-xcom which utilises internet connection. I would not even bother making this, if i did not knew that one day he will make this into a proper multiplayer project.

Would there be a way to update this so if you both own the game it'll be a connection instead of steam? That way you could have "Hidden activity" between turns instead of a trust system.

So far, i say great work! I hope this can get far and be a true successor to Ufo:tts which i still have kept hold of 0.99 to this day (since 1.0 was never official)

SnorkelingTony @snorkelingtony

is there a way to modify the score penalty for turns taken?

misterjopp1635872573 @misterjopp1635872573

Well, now not really. But you do raise a good issue. I'll look for a way for it to be modifiable in future releases.
Do you consider it to be too low, or too high?

SnorkelingTony @snorkelingtony

its at a perfect rate i was just curious if there was a way to modify it.

misterjopp1635872573 @misterjopp1635872573

there is now. In battlescape options you can even set it to 0.

Unfortunately, this being based on the original OpenXCom means sacrificing the QoL improvements and enhanced modding Extended brings. But this is still brilliant stuff. Even without netcode, screen-sharers like Parsec could be used for online counter-op.

*still dreaming for player-controllable aliens in the Geoscape for a FULL versus campaign*

Bulletdesigner @brunoantunesarq

sounds kool, gonna try it

Hobbes @hobbes

And we have another XCOM multiplayer after UFO2000 was released 17 years ago.
Congratulations :)
