Hi, I'm working on a few ideas.
Adrift, you are the lone survivor of a shipwreck and drifting at sea on a raft constantly circled by sharks.
Dead Drop. You are spy who has been caught. You are trying to make it through your interigation. Unfortunately they have all your encrypted reports you sent to mother Russia and are playing them back to you one by one.
Ransom note. Send daily instruction to the people you are blackmailing. Use a way of disguise your voice for your daily log.
Cascade. You work for a corporation that has been hacked and it's all your fault. Tower represents the files and systems of your employer been hacked. It's a race against time to save as much as you can, repel the hack and cover up your involvement. Cyberpunk setting.
