A couple of Aliens games that went missing over the holidays have returned to Steam.
SEGA had nothing to say on the topic, but as it happens, both games are now available again - after less than a week of absence. We expect them both to turn up on other digital distributors if they haven't already.
Given the date of the mysterious disappearance, it's almost certainly a matter of licensing deals expiring and being renewed. Not especially exciting stuff, alas.
