Giza

Giza is a first-person shooter set in the Giza pyramid complex, in the year 2027. The American government has struck a secret deal with the Egyptian government to purchase the pyramids of Giza for US$20 billion to harvest a unique chemical compound from the stones, which will be covertly harvested and replaced with carefully-disguised concrete. You are an American Egyptologist sent to oversee the project, and you go without protest, hoping to somehow sabotage the project. At nightfall of your first day there, an elderly Egyptian man approaches you, reveals he knows of the project, and tells you that you must find the lost tablets of the sun god Ra in the pyramids to save the pyramids and the human race.

The game takes place within a series of single-storey, grid-based mazes filled with hazards and useful items. Rather than defeating all enemies, or finding an exit to complete a level and advance to the next, the player must find four stone tablets that match to complete a picture. Although there are enemies in the game, they are all dispatched in a single hit, and emphasis is placed on puzzle-solving and navigation.

In addition to doors, each level is filled with color-coded blocks that can be destroyed with the corresponding colour crystal found somewhere in the level. Clearing these blocks is necessary to progress through the mazes.
