Cadet Williams was tasked directly by General Mudd in Troop Commander: Slime Invasion to defend a roadblock. An alien slime attack is expected, the invasion of which took place the day before. After listening to short instructions, you need to move on to action. The cadet has a small detachment and a set of equipment at his disposal. You can select it at the bottom of the screen. The squad will act without your participation, like tanks and cannons, and you can control the cadet by making shots and moving. Troop Commander: Slime Invasion is similar to defense towers, but with a significant addition - you can control the main character.
