In Escape from 100 Million BC, players take the roles of stranded time travelers who are hurrying to reassemble their ship because a nearby volcano is about to blow. There are also dinosaurs to dodge, time rifts to close, and historical figures to round up who got caught in the wake of the passing time ship. Each player has unique abilities and stats which will aid in repairing the time ship. Players must be careful not to disrupt the timeline too much or the volcano will detonate, wiping out proof of the expedition altogether.
