UFO Online is now in open beta testing, offering the chance to sample gamigo's tactical MMO browser game and help protect the Earth from extraterrestrials. Here's word on the game:

A mixture of flash technology and a Unity Engine ensures for crisp detail 3D graphics sets the scene well for both the soldiers as well as the Skum. Graphical improvements were also undertaken for effects, for example with the weapons. Performance was once again optimized, especially regarding the flash part of the game. Users can also look forward to an improved interface with expanded functions like drag and drop and keyboard shortcuts.

In the turn-based, tactical battles the people who win are those who find the right mix between tactics and research. In the long run it's all about achieving world domination with one of the three factions.
