X-Hour: XenoStrike is an action point-based dice allocation game in which you command an elite combat team in Advanced Personnel Exo-Suits, affectionately known as APEs. Your mission is to exterminate Xenomorphs that have infested a facility before it gets overwhelmed by their incessant spawning. The Xenomorphs have anticipated your team's insertion and have positioned Xeno Sentinels to guard their spawn sites, while a Xeno Prowler roams the facility, hunting your APEs.
