It's titled Zombcopter and it's an endless shooter, where the player is operating the rotating turret of a helicopter to protect the last remaining intact building, the Town Hall.
We've taken a more comical and funny approach regarding this game. The mood is quite silly with airplane and quad bike driving zombies in hotdog costumes and such.
The game has roguelike elements to it in the form of different random upgrades that you can choose from gradually as the game progresses.
Currently there are 28 unique upgrades, but some of these might occur more than once, so you never run out of upgrades to choose from. These include new weapons, weapon upgrades, barricade upgrades, general and unique upgrades.
The power level of the enemies are increased as time passes and eventually it becomes impossible to defend the Town Hall against them, the better you choose and combine your upgrades, the more zombies you can kill until this happens.
There are 9 zombie types that behave differently from each other, sharing the only similarity that they have a brainless tunnel vision on destroying the Town Hall.
There are 50 completely different visual representations of these zombies so they don't really feel repetitive.
The game contains a fully narrated Tutorial that you can opt to try from the absolutely simple "main menu".
Once the game is over you can check a quite detailed statistics about the session you've just played.
