Trog (prototype, rev 4.00 7/27/90) — About this game
Trog (prototype, rev 4.00 7/27/90)’s revision 4.00 prototype uses an indirect puzzle-and-strategy approach. The player controls a hand that lays bones to guide the corresponding dinosaur along a route, rather than steering that dinosaur through the final game’s egg chase. This bone-guidance design predates the change made after location testing, giving the prototype a different form of player control.
