About this game
Test Subject is an intense single-player first-person shooter that throws you into the role of an ordinary person caught in an extraordinary situation. One moment you're living your normal life, and the next you're abducted by beings not of this world. With no choice but to fight, you must rely on your wits, your fists, and the power-ups you scavenge as you attempt to escape a labyrinth-like alien ship filled with danger. Every encounter tests your strength, resilience, and determination to reclaim your freedom.

Game Progression and Saving System:
The game features five distinct levels, each designed to challenge your skills and determination. Levels must be completed sequentially—finish one to unlock the next. Along the way, you can collect power-ups that enhance your abilities. These power-ups will be permanently saved once you complete the level.If you’re defeated before reaching the end of a level, you’ll restart from the beginning of that level. The game employs an automatic save system that records your progress at the end of each level, ensuring you can pick up where you left off.
