Long-in-the-offing DS side-scroller Aliens: Infestation launches on 30th September.
According to Joystiq, a US release for the WayForward-developed title will then follow on 11th October.
Wayforward know their platforming onions so it could be worth a look. The studio's past credits include the lovely Wii update of A Boy and his Blob, DS brute Contra 4 and recent DSiWare favourite Shantae: Risky's Revenge.
Published by Sega, Infestation is thought to be a reincarnation of a cancelled DS take on Gearbox's forthcoming console shooter Aliens: Colonial Marines, which is due out next year.
