Xbox Live fans are in for a treat this week as two games arrive tomorrow as part of the Xbox Live Days of Arcade promotion. Puzzle Quest: Galactrix will be available for 1600 points while Flock! will cost 1200 points.

Flock! sees players piloting a UFO and herding livestock into the Motherflocker. The game features over 50 pastoral puzzles where players must pick up wood to form bridges, move boulders to create obstructions and flatten fields to create pathways to help herd the animals before time runs out. You can flock together thanks to the two player local co-op mode and the level editor means you can even create and share your own levels online.

Puzzle Quest: Galactrix from D3 Publisher features online multiplayer, matchmaking, leaderboards and voice chat. Set is a new futuristic science-fiction setting, the game features a new hexagonal puzzle board, allowing players an “extra layer of strategy” while the upgradeable spacecraft options allow players to create, develop and customize the fleet.

For all you PS3 gamers out there, don’t despair because Puzzle Quest: Galactrix will be arriving on the PlayStation Network this Spring while Flock! will be released on the PSN this Thursday.
