“I remember playing this well over a decade ago now back in my high school days. It was good fun to play with friends and wasting some dinosaurs. After trying it now in 2026, Its dead to say the least. If you can get some friends together, This would be a fun cheap game to enjoy…”

“While nobody really plays this game anymore, its just a mindless fun game. Not a lot of depth, but lots of action.”

“Oh, it's one of those flawed fun games. Now you can only play it solo, unless you have people who want to play this one. Some mechanics are very wonky. Most of the times you shoot dinosaurs and have no idea what is going on around you. Fun for 30 minutes.”
