Adapted from the Universal Combat franchise, Hostile Intent - Planetfall boils down the expansive space exploration of UC into an intense action game. Players can engage in combat in both open-space and planetary surface encounters, exploring the galaxy in interstellar and planetary excursions and taking on opponents in first-person shooting and vehicular combat phases. Players can also upgrade their characters through skill-based upgrades as they continue to conquer. Hostile Intent runs in part on the Reality Engine and SpeedTree RT technology engines.
