UFO Screenshots
It is the year 2084. You control a secret organisation charged with
defending Earth from a brutal alien enemy. Build up your bases, prepare
your team, and dive head-first into the fast and flowing turn-based
combat.

UFO: ALIEN INVASION is a squad-based tactical
strategy game in the tradition of the old X-COM PC games, but with a
twist. Our game combines military realism with hard science-fiction and
the weirdness of an alien invasion. The carefully constructed
turn-based system gives you pin-point control of your squad while
maintaining a sense of pace and danger.

Over the long term you will need to conduct
research into the alien threat to figure out their mysterious goals and
use their powerful weapons for your own ends. You will produce unique
items and use them in combat against your enemies. If you like, you can
even use them against your friends with our multiplayer functionality.

'UFO: Alien Invasion'. Endless hours of gameplay -- absolutely free.

The game takes a lot of inspiration from the X-COM series by Mythos and
Microprose. However, it's neither a sequel nor a remake of any X-COM or
other commercial title. What we as a team wanted to make is a brand new
experience that tries to surpass the quality of games from 1992, rather
than simply recreate them with flashier graphics.

We also believe that open-source projects don't
need to be disorganised or badly-managed. We work together in a
friendly and professional way, with a clear vision for a game that we
know is worth playing.

Hello Devs, I've loved all your hard work since the very beginning!

Since my brother and I are huge fans of this rare genre, will you add Local Co-op vs. A.I. where we control 2 different squads? Also can you add a Local vs. mode for those of us who don't mind taking turns on the same screen? I'll be playing with my brother and we'll never cheat ;)

Voted only for you in the TBS category! thankyou

Our multiplayer (coop and adversarial) needs a lot of work. 2.5 won't see any major changes but I'm hoping we'll get to it for 2.6. A way to host local games would be nice, but we will probably focus on improving the regular multiplayer functionality first. If you've got a decent computer, you may be able to just install the game to two different locations on your computer and switch between them to approximate local multiplayer play.

@Guest: We're still in the middle of 2.5's development cycle, so I don't expect a stable 2.5 release soon. If you're on Windows you can download nightly builds of the development version:

The simple campaign is an early work in progress. I would stick to the regular campaign. I can't answer your question because I don't actually know what the simple campaign does. Hopefully that will get fleshed out in the future.
