Alien Breed Trilogy
is a compilation of the three games in the series' reboot that were previously made available separately:
The Windows version merely bundles the digital copies of the individual releases to download, while the Xbox 360 version is a retail release. The latter has the three games on a single disc and adds a menu screen where the titles can be chosen. There are no other additions and the achievement total of 600 points (three times 200 as for XBLA titles) is lower than the 1,000 generally reserved for retail releases.
