Game is still in very early development as there's a lot of placeholders & experimental mechanics. Any feedback is appreciated

The dead are coming and there's no way out
Block, barricade and use whatever you have at hand to stop them taking your guts out. Use a hammer to build intricate barricades with what was left behind, tables, crates, doors or anything to stop them turning you.

Upgrade your arsenal
Fight the zombies to earn cash each wave and acquire guns, ammo, and any gear to deal with the next wave's surprises with the help of an ominous trader, providing a variety of calibers to suit whatever is needed next wave.

Choose your approach and survive
Have the learnt skills of a combat veteran to deal overwhelming firepower to the undead team, the professional knowledge of a engineer to supply and fortify your team, or the medical expertise of a surgeon to patch up your team when it becomes too much. Pick whatever role seems fit for you and help your team survive the onslaught together.

No one will survive alone
Proximity voice, team radio and trust in your team will be needed to survive, communicate each others needs and work as a team if you want to have a chance to survive, since strong collaboration between the three roles will be needed for what's yet to come.

They will know
The dead are bizarrely smart, and will know what you've built and haven't built especially if they are composed of your dead friends. They can and will exploit any possible weakness that they can to get the upper hand with the use of extensive different types of zombies, strategies and a "Hivemind" to control them all.
