Mesozoic Protocol

A tower defense game where the dinosaurs evolve. The more you fight them, the harder they hit back, adapting against what you throw at them to keep you on your toes. Spread your damage sources, find combos, or watch how the horde over-runs and kills all your hopes of containment.

The research experiment failed, the lab's breeding tanks kept going even as the humans left, the dinosaurs escaped into the wild. Out of the lab, the dinosaurs started merging with the machinery, kept breeding outside of their tanks at an alarming rate.

The only hope left is the Mesozoic Protocol.

An emergency protocol, designed to keep the breach in check and contained until the scientists can figure out a way to undo what they have done. You are in charge of it.

At your disposal are different tower types. And you will need them all: Pulse, Chain, Cryo, Mortar, Flame, and a support Hive. Different damage types to combine in a myriad of ways. But the dinosaurs have built in resistances, and come with tricks up their sleeves. Soon they evolve. Evolution will find a way to make your life harder. Over-use one tower and you quickly find that the dinosaurs will crush you.

Mesozoic Protocol has hand-designed outposts, meandering through different biomes, everywhere you are trying to stop the dinosaur herd from running over the rest of humanity, while the scientists are frantically trying to undo the mistakes of their research and what they have wrought onto the world. You are just buying time for them in a containment fight against something the world hasn't yet seen and is not really prepared to fight. Will you keep humanity from perishing?

Difficulty tiers range from Easy (is this a tutorial or what?) to Extinction (you will think the game is unfair, and wonder why you chose this suffering).

There are additional Breach and Containment Modifiers per level, so you can replay your favorite levels with an extra challenge. Breach bans some of your favorite towers and rewrites the wave list: more dinosaurs, and heavier ones, sooner.

Containment leaves you with only one life, locked loadout, no selling of towers. Lock in your strategy and survive the onslaught of dinosaurs in one final test of your skills. Every star is earnable.

You think you can beat the game on Extinction difficulty in Containment mode? Think again!

There's also an Endless mode that escalates forever so that you can keep honing your strategy until eventually the dinosaurs become too strong and overwhelm you regardless of your efforts.

There are also different boss waves, that will push you and your strategy to the limit. Some bosses on Extinction feel barely survivable. They are. Winning anyway is the point.

Collect bolts to unlock all the mech heroes and their abilities. You get one for free, unlock the rest as you play and adapt your gameplan based on what the dinosaurs throw at you. Different mechs fit different strategies. They complement your tower setup and become part of the bigger plan.

A persistent meta tree helps you level up your towers as you progress. Spend stars that you earn on level completion to improve your tower setup until you have everything unlocked and can match the dinosaurs as they keep evolving. Feel the progression and how your towers become stronger and stronger across runs.

There are easter eggs scattered across the outposts. Look around and see if you can find them all.

Early Access

The game is playable from start to finish today. I am one developer, and I want feedback from players on balance, difficulty and new content before I call the game finished. Early Access lets me make those changes together with the people who play it.

I plan to add more levels, more enemy types and more languages. I also plan to tune balance and difficulty based on player feedback. These plans can change as the game develops. Early Access should take about 6 months; the final length depends on what players report and ask for. I plan to raise the price when the game leaves Early Access and version 1.0 ships.

The free demo plays the opening outposts. Download it below, or play it in your browser at play.mesozoicprotocol.com.

Developed solo. Built because I wanted to play a tower defense game where the enemy actually pushes back and adapts to what you do.
