Description
Happy Room: Log brings the chaotic lab testing simulator straight to mobile devices, placing you in a clandestine research facility dedicated to inventing deadly weapons and lethal contraptions engineered to wipe out living targets. While the previous installment let players experiment on human test dummies, budget constraints have forced the lab to cut costs. This time, your guinea pig is simply a wooden log sporting a safety helmet. Aside from that hilarious switch, you still enjoy the full arsenal of destructive traps and creative tools to satisfy your mayhem-fueled experiments.
