Bikini Alert

Bikini Alert is a run and gun action game challenging you to survive against waves of several kinds of robots responsibles of the confinement of humanity to the underground. No one knows exactly who created these machines or what their objectives are, but famine has forced humanity to fight back!

Cyne Rizerous, knowing nothing of the outside world, nor being able to enjoy the gigantic sky, is a brave man who decides to enlist for the battle and save the last Supply Collector Team. Rizerous is the owner of "Leviatan", a car which can be swapped at will with a heavily armed robot, but his curiosity may lead him to some hidden truth about human past.
