Tri-Heli II

A horizontal scrolling arcade and strategy game. You control the helicraft and must collect diamonds one at a time and return them to base. Just to make life more difficult, the diamonds are buried underground. You must use bombs to make holes in the ground then manoeuvre the helicraft into the hole to collect the gem! Slow moving asteroids descend from the sky and contact with them destroys your craft. Once a level has been completed the ground becomes higher and so your task becomes even harder, but each time you return to base you top up your supply of ammunition. Includes full assembler source code.
