Hello [K40$]-Spectre. In my opinion, Crawler is a decent map. It was well polished, with very many custom models, a custom selection circle, and a cool attack system. I liked the intro cinematic, especially the tank landing on the helicopter pad. The gameplay at first impressed me. I liked the feeling of three units firing at the same dinosaur. I also liked the somewhat random placement of shops. It made it feel more realistic. I also liked how you could add to your attack by purchasing more soldiers and how the soldiers actually stood up on the top of the tank. This brought a realism issue to the game though. The flying enemies should attack the soldiers, not the mobile fortess. Why on earth would they attack a heavily armored tank when there are exposed soldiers on the top? Maybe you could add health to the soldiers. I also liked all the enemies you made, except the lightning attack of the Stegosaurus. I really think you should remove that. I also want more types of dinosaurs. Maybe you could also add young and baby dinosaurs. I liked the idea of competing against the Poachers, although I wasn't sure if I was supposed to kill their headquarters. Also, my soldiers continued firing at it when I was near it. I also got pretty bored of the map after forty or so dinosaurs. Perhaps you could decrease the maximum kill count?
All in all, you've made a decent map.
4/5 from me.
