About Protocol
Protocol is a sci-fi comedy with elements of horror, action and a twisted love story. You play a soldier recruited for the Protocol program, whose objective is to make first contact with an alien life form. The story takes about 9–12 hours.
The Protocol program
Set in the near future, the game places you in a landing box and drops you somewhere in the Arctic Circle, near the Terminus research complex. A mysterious AI gives you orders to carry out first contact as part of the program. Any deviation counts as a Protocol violation and leads to the elimination of you, the complex and its staff; the description also warns that violations can result in the elimination of the entire operation.
Choices and challenges
You uncover a plot involving conspiracies, twists and dark humour, with expletives and light-hearted mockery. The game can leave you facing deadlocks where death is the only way out, and may require you to replay moments repeatedly. Even a snowball can be lethal.
