The graphics are fantastic – from realistic landscapes the world over to hundreds of aircraft ranging from the very latest big airliners to fighter jets. Comes in Windows Mac and Linux versions.
An old-school deathmatch first-person shooter with modern features such as a rich colourful and arcade-like atmosphere and a retro Sci-Fi feel. The makers say: “This game combines some of the best aspects of games such as Quake III and Unreal Tournament and wraps them up with a retro alien theme while adding tons of original ideas.”

Play nation-builder! FreeCol is a turn-based strategy game that’s a clone of the celebrated classic Sid Meier’s Colonization and similar to the newer Civilization.

Will you help your colonists create a great new nation or a banana republic?
