“	A 2 player tycoon about surviving and zombies. The game saves in a way where the red owner door is a separate save from the purple owner door. Find a bug or have a suggestion? Well at the time you could message me, but you can't anymore.	”
	―- Game description

Zombie Survival Tycoon is a co-op tycoon survival game created by Zack81312 in February 2021. It is one of the first working tycoons in RetroStudio, featuring two-player tycoons in red and purple. Development eventually ceased, causing the playerbase to die out and break in several ways.

Gameplay

Players spawn in a ring-shaped valley surrounded by gray mountains and a stalagmite-style stone tower with a hangout area at the top. There is a rusting barricade in one direction and four tycoons. Each tycoon is fit for two players, who can either join Red or Purple. Red is in charge of decorating and fortificating the tycoon, while Purple builds the structures. Regardless of either side, you will always be able to build your own conveyor. You can fight off zombies of different types outside the tycoon, including Brutes(slow, beefy), Sprinter(fast, weak), and Zombie. A zombie apocalypse happens every 10 minutes.

Tycoon

The tycoon starts with the first floor, which includes basic gear, furniture, and droppers. In the basement, there are more conveyors to produce survival goods. On the second floor, there are more defences, new conveyors, but also "helper printers" to help the other owner earn more money.

To the side is a garage with a "Deco Chassis", costing ten thousand dollars, being a simple plain car. There is a tunnel marked WIP behind the base and a ladder to the back clifftop, but both are inaccessible. Base defences are few, with fences that have entrances and can easily be climbed by zombies.

Valley

Players can spend $2,000 to unlock the valley for the whole server as long as it stays open. Because of the travel length and difficulty, bring a pistol and/or sword, and your Deco Chassis. The first few zombies can easily be outrun if you keep driving. You are forced to abandon your car at a broken gate because it cannot drive over.

One will find themselves in a circle-shaped valley like the one in the main game. There is a large green button which will spawn a Gargantuan zombie that spawns minions to attack you. His health is 10,000, requiring 500 pistol shots for 20 damage each. Scale a tree and consider an autoclicker if you want an extra $25,000. If not, run to the next gate.

Once reaching the end of the valley, a Noob camping there says that there are hideouts the player can build for more control. It costs $20,000 to begin, but it does nothing. At this time in development, it has very little content as said by the owner.

Bugs

The tycoon has not received updates for most of 2022. Many buttons are not purchasable even with enough money or have incorrect prices. For the most part, the game is unplayable or unenjoyable because of how much money you need with the little droppers you can buy.
