Eliminating the threat in the LabBuster laboratory turns clearing premises into a test of your accuracy and ability to collect first aid kits in time among the wreckage of equipment. You have to break through the compartments, trying to quickly destroy the mutants. Carefully monitor your ammunition level and pick up dropped equipment in time to avoid being surrounded by enemies and quickly prepare to meet a new wave of dangerous creatures. For each elimination of a monster and successful survival in the corridors in LabBuster, you are awarded game points. A quick reaction to sudden attacks from the shadows and correct calculation of the reserve of strength will help to cope with the growing aggression of the test subjects. Your ability to skillfully fire on the run will be the key to restoring order at the facility.
