A strange virus emerged on Skull island and swept across it. This virus caused all of its inhabitants to, human and beast, to turn into savage zombies, attacking everything and anything they see ( except anybody who’s already been zombified ).

It is at this time, by coincidence, a number of Triremes crash onto the coast of one side of the island. On board, Leonidas and 300 Spartans. On the other side of the Island, Jack Sparrow and his crew on board the HMS Interceptor decided to dock on this strange island.

The Spartans begin heading inland as they have no supplies to survive very long on the island. 300 Spartans Warriors soon find themselves surrounded by heavy jungles. Sparrow and his crew remain by the coast, onboard their ship. Sensing the disturbance on the island, hordes of zombie beasts begin heading towards both locations.

Human Zombies ( Wave One ): 25 fast moving Zombie Natives.

Insect Zombies ( Wave Two ): This wave attacks about half an hour after the initial wave, giving each group time to think about their next move. 50 Insects ahead towards both groups location. This group comprises of a mix of zombie bug-beasts ( giant spiders, giant centipedes, arachno-claw etc. )

Dino Zombies ( Wave Three ): There is an hour preparation for this attack. 15 Venatosaurus and 1 Brontosaur

Revived Zombies ( Wave Four ): This wave occurs only five minutes after the previous. Everyone who has died so far come back as zombies to attack their own respective groups.

Ape Zombie ( Wave Five ): This wave begins after half an hour. A zombified Ape giant ( Kong ) heads towards each groups location.

*If both groups are still alive, waves will cycle through over again ( this time with twice as much zombies from before ).

Note: Neither group actually has to engage and kill every zombie in each wave, They merely have to survive it.

Which group survives the longest?
