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.
