ArchaeologyX

Archaeology X is an open world Archaeology exploration game where you dig for ancient treasures, relics.
Use your notebook and research to discover items ancient hidden for 1000's of years, also explore long lost caves or tombs.

Realistic digging, archaeology, into different types of earth and rock to dig through, features like using torches when exploring underground areas/tombs, use vehicles or animals to travel, or swim (mind animals like crocs though).
Use your research from your notebook to discover clues where to dig (relics/treasures might not always be in the place you expect! Won't be easy to find them), e.g. decipher hieroglyphs, or try to match possible locations from sketches.

Be brave, go out at night or get some sleep in your tent.
Meet other local people in game, chat to them, locate a radio station to send messages via radio/telegraph to your home about new discoveries made.
Scavenge food and water to survive, sell or buy food with money you make.
Visit shops to buy/sell food/treasures in other towns, or go to the museum to display your treasures found (bear in mind these may not be located close by but other towns or areas, meaning travelling and discovering).
Watch out for dangerous animals or thieves that could hurt you, steal your loot.
Mark your dig sites with tape in case you want to come back later, remember your last dig area.
Be careful with digging, you might break the fragile relics.
As you dig if you discover something of interest you should dig close up and carefully not to risk breaking the relic.
If walking is too far then use other forms of transport available to go to other areas faster, such as cars, horses or camels.
