High Entropy: Challenges

High Entropy: Challenges is a standalone action-adventure FPS with a beginning, 15 levels, a default ending and a special ending for completing every level with a 100% score. You use computers, unlock doors, crawl through vents and deal with enemies by fighting them head-on or finding other ways to neutralize or avoid them.

Solve the levels

Computers can be used through graphical interfaces or a command-line interface. The command line offers a way to overcome some obstacles, but levels are designed to provide an alternative route forward, with one exception: an introduction in level 7. The exact commands needed there are written in a document beside the computer. Some secondary objectives and achievements require command-line use, and manuals placed throughout the levels introduce it gradually.

Some levels offer multiple approaches, including action-oriented and stealthy routes. Achievements include Path of Fists and Path of Shadows.
