The giant worm has more advanced mechanism. You can not kill it before you destroy its hearts. If you shoot it the bullets will reflect and not cause any damage. Destroying a heart will reduce the spawn number of the smaller worms. Small worms move towards the player when they fall on the ground. Once the heart is destroyed the veins will start to bleed and you will have to be careful to not get hit by the blood drops. If all hearts are destroyed there will be no more spawning of small worms but the giant worm will start shooting poison.
Here is a new game update with more game objects including: ladder, bridge, bridge lifts and factory. The ladder will lead you out of the cave. There are two scientists waiting for your help in the houses over the broken bridge. Jumping on the bridge lift is dangerous and you have to react very fast before it breaks.
Ranbo - my new retro-style shooter game created in Java programming language using Eclipse SDK. In this game you will be fighting genetically mutated animals. The first mission of the game is to rescue five very important scientists that can help you save the world and destroy all the monsters. The game can be played in one player or two players mode using keyboard or gamepad. It took me five days to make this all. There is still much work to be done.
