Trog is a classic arcade game released in 1990 by Acclaim. You are a dinosaur collecting your eggs, protecting them against the cloned Trog cyclops. I couldn't show the excellent multiplayer mode in this game now, but it's there. Do you think the gameplay is a little familiar? Well, that's because it's similar to Pac-Man and Amidar.
From searching the Web, I learned there are MS-DOS and the arcade original versions of this game as well. Enjoy.
