Alien Syndrome isn't exactly the most memorable game in Sega's back catalog. While marrying Robotron-style top-down shooting and hostage rescue with the Alien sci-fi aesthetic seems like a great combination, in practice it was a slightly-above-average arcade action game that saw a few ports and was quickly forgotten.

This 3D remake is far less faithful to the source than many of the early SEGA AGES releases, but in this case it's probably for the better. It adds proper twinstick aiming and more interesting (and gruesome!) boss fights, though the backgrounds have gone from washed-out pastels to near-invisible darkness. Definitely one of the better efforts from the series, and much more playable than the reboot that came out a few years later.

Saw a US release in the Sega Classics Collection package, though it was removed from the PAL version for age rating reasons. Includes the standard info card, which has comments from the original game's planner, Hiroshi Aso.
