HIGH ENTROPY: CHALLENGES
Use computers (via GUIs or the command line), unlock doors, crawl
through vents, fight enemies head on or find other ways to
neutralize or avoid them...
High Entropy: Challenges is a free, action-adventure FPS (inspired
by some of my favorite immersive sims) consisting of a beginning,
15 levels, a default ending and a special ending if you finish
with a 100% score in all levels.
