'The Last Circus' is a 3D Tower-Defense game for PC.
Aliens have made first contact with the earth. They are abstract and non-communicative collection drones. And, for reasons no one understands, they only target circuses.
In this game, you play as Hopsworth, the ringleader of the only circus on earth still unreached by alien claws. With your finely trained animals, you set up a defense to prevent being overrun by aliens. The aliens have realized Hospworth is the reason for their failure, so they've made capturing him their target in all missions of the game.
Position your animals around Hopsworth's tent, based on the mission's predicted enemy path. And they'll attack enemies as they come in.
Animals have different skills. Elephants attack slowly but with a huge area of impact. Lions can bypass all shielding effects, and Gorillas can slow down the enemies' paths. As the animals get used to battling alien scrap, they'll earn XP the player can invest into making them stronger.
Winning conditions would be defending Hopsworth against a certain number of enemies. Losing conditions would be a certain amount of enemies reaching Hopsworth, overwhelming and capturing him. Don't give up, and protect the last circus on Earth.
