Grid Runners involves hacking all the terminals in each stage (grids), but the real challenges are in resource management and environment manipulation. You can hack each terminal in one of four ways: to grant access to nearby doors, to disable nearby lasers, to recover your link (health), or to get you extra time on the grid. Enemies can shoot at you to deplete your health and disconnect you, and lasers will reduce your time allowed on the grid.
Requires OpenGL 2.0+ and at least 960x720 resolution (windowed mode). Debian/Ubuntu packages provided.
