Although Intensity revolves around a rescue mission, it also involves a certain amount of profiteering. When you rescue enough colonists, giant ‘Rs’ – resource units – appear on the screen, and the ones that you collect can be spent on upgrades.
The aliens attacking Intensity’s space stations start off as fairly benign Spores, but they soon mutate into colonist-attacking Stalkers, which can then evolve into drone-targeting Nuclons or gestating Podules that turn into skimmerhostile Trackers.
