After beating the second game with this character this one is the first one to use the man with the top hat. So to begin you have to defend an elevator with a gun at first then use the money you get from killing enemies to gain money to upgrade your elevator. You can use it to buy turrets ranging from machine gun turrets to laser guns. Some turrets don't do the damage they just push them back. You can upgrade them to make them more powerful. There were a few times I made a mistake and sold them. Each amount of days you do you get extra floors to defend. You can buy more elevators to defend yourself some more. The enemies are the same as the sequel they start off as small blobs to large ones. You have 15 days to defend your self and then it's over. I give this game a 8 out of 10.
