About Test Subject

Test Subject is a single-player first-person shooter about an ordinary person abducted by beings from another world. Trapped aboard a dangerous, labyrinth-like alien ship, you fight to escape using your fists, wits and scavenged power-ups.

Fight and progress

You vault over obstacles and punch aliens, and solve puzzles required to advance. The game has five levels that you complete in sequence, with each level unlocking the next. You can collect power-ups to enhance your abilities; they are saved permanently when you finish the level.

Levels and saving

If you are defeated before completing a level, you restart that level from the beginning. An automatic save records your progress at the end of each level, so you can continue from where you left off.

Frequently asked questions

Steam lets publishers create keys to sell in other shops. Once you activate a key, the game is yours to keep, just like a store purchase.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
