Doom Pit

In the game, you control an archaeologist on an expedition aiming to retrieve artifacts left by an ancient and mysterious civilization. You carry a spade, which works as your primary weapon against the dangerous creatures that roam the excavation site. From level 2 on, you can buy yourself a pump-action shotgun to blast the monsters into oblivion, a couple of shots will be enough to dispatch even the hardest foe! Unfortunately, it won’t work underwater. Also beware the ghosts of fallen researchers whose lives have been claimed by the cave's maze. You will recognize them because they look just like you, but glow in the dark. They cannot be hit, so you will only be able to avoid them.

You have to find all the artifacts and bring them back to the tent in the starting screen. Pick up artifacts by pressing the Up key or by pushing the joystick up. Press the Inventory key (available when you are carrying at least one object or artifact) and select artifacts you want to drop. You are allowed to carry a maximum of 100 units of weight. Your spade and primary oxygen reserve are always with you and do not count towards it. Artifacts found weigh 30 units each, except for the Gem, which weighs 80. Items of equipment weigh 20 units each. The Gem is always kept by a mighty Dragon spitting lethal flames.
