The rag doll will become a test subject for extermination agents at Lab Havoc. Before starting the test, you must place mines, traps, firearms and other means of destruction in the room in such a way as to cause maximum damage to the doll. Click on the triangular start button in the lower right corner and watch the process. Every injury and blow will be counted and converted into coins. Remember that all the items that you will place in the room also have their own price in Lab Havoc.
