An update to the Natural Selection 2 Website has a bit to add jetpack to the action/strategy sequel in development at Unknown Worlds. Here's a bit: "This week we also want to show you the Jetpack in NS2. The Jetpack is a late game marine upgrade that allows players to fly for short distances, get into vents and stay off the ground, away from snapping jaws. It is researched at Advanced Armory which then has a "prototype module" attached to it (tier 3). Once researched, players will be able to buy jetpacks from any armory they visit." Thanks Big Download.
