The game has an auto-fire button, lock button, Weapon, and these all can be hidden with just one click so that you can have a better and bigger game screen to play. It has more than 25 species with amazing features. If you choose the lock button, it will shoot only those species which you have chosen and after killing, it will shift to the other one unless you choose by yourself. You can increase or decrease your bet from 0.05 the minimum to 5.00 maximum. You will see a different arrangement of the species once the wave comes and wipe all the previous species. The game is fun to play and has lots of fortunes. The graphic is amazing with some amazing creatures lurking on the screen/surface of the ocean.
