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.

A new game I'm working on is now available for Android. If you like the game, please rate it.


CaveExpress is a classic 2D platformer with physics-based gameplay and dozens of levels. Master your pedal-powered flying machine to pick up packages from your cave-dwelling clients and drop them off
at the collection point. But beware! Mighty mastodons, terrifying pterodactyls and others would rather see you extinct.

I'm also working on a Windows version released on Desura. It will be available soon.

We're starting to see the end for 2.5, but to be honest I don't want to get your hopes up. The final steps for a release can take a while and there's still a bit of polishing left, so I wouldn't expect it too soon.

The 3D air combat is still just one person's experiment and is a long way from any implementation. I don't know about 2.5's schedule, but we probably don't have many big things waiting to be completed.

Never get any replies there.. lol

But I think I've sorted it, played a couple of missions now and it hasn't crashed.. yet. UFO doesn't like high resolutions it seems, I've managed to get it up to 1280x768 without it crashing now. It gets laggy at times in some missions which it shouldn't really, I've got a Radeon 7970. I can play Metro Crysis 2, well what ever you want to name on ultra full whack without even a hint of a stutter yet UFO lags.. strange stuff.

Definitely something to do with it not liking the resolution.

But other than that I've really been enjoying this game, recommend it to anyone. Cept Ubuntu users with good graphics cards who want a decent resolution ofc :P
