Originally created for the '7 Days FPS' challenge, Deadlock is
an FPS that features both puzzles and platforming. Here, the
goal is to advance to the top of an enormous tower without being
unceremoniously booted by the security system. Along the way,
you'll be called upon to solve environmental puzzles, deal with
A.I driven robots, turrets as well the fact you cannot actually
destroy anything you encounter. At best, you'll be able to
temporarily stun them.  Official site here or go on and play the
current build of Deadlock for browsers, Mac, or Windows.
