About the game
Scientific spaceship Saratorum drifts near the planet Nadalon. An alien craft appears out of nowhere. All attempts at communication fail. Time passes, and crew members, one after another, start to act weird. It was already too late when you gathered your courage and decided to act.
Now only your weapon can help you warn your Homeworld about the alien threat.
Inspired by Zero Tolerance and classic retro shooters:
• 5 inventory slots to manage your equipment
• A wide selection of weapons
• Levels that demand different approaches and tools to complete - sometimes speed, sometimes caution, sometimes special gear
• Bosses and enemies with unique weaknesses and tactics
• Cutscenes connecting levels with the storyline
Originally made for PSP in 2025.
Full PC Steam port to modern systems.

Common questions
Does Locum Tenens have Russian language support?
Voice-over: English. Interface and subtitles: English.
What is a Steam gift and how is it different from a key?
A gift is a present our bot sends straight to your Steam account via your profile link: no code to enter, the game appears in your library once you accept the gift. A key is an activation code you enter yourself in the Steam client.
Which gift region should I choose?
The one your Steam account is registered in: Steam will not accept a gift from another region. The region is shown in your Steam account settings under "Store country". "CIS countries" means Belarus, Armenia, Georgia and other CIS countries.
How will I receive the gift?
After payment you enter a link to your Steam profile and the bot sends the gift straight to the account — you only need to accept it in Steam. It usually takes 2–5 minutes, around the clock.
What if the account already has this game?
Steam will not let you accept a gift of a game already in your library — check the library before buying. If it happens, write in the order chat: we will refund you.
