Sewer Rat is a split screen multiplayer rat experience / passion project that explores the hidden lives of rats and their unique social construct. A mix of realism, silliness and straight up rat propaganda. It's currently in the alpha stages of development.

What the developers have to say:

Why Early Access?

“I fell so madly in love with Sewer Rat when I started working on it. It's been such a large part of my life the last year and I really want to share this project with others. While I am very set on a path for Sewer Rat's story, I didn't want to make a multiplayer rat game just for myself. It would be nice to get community input as I developed more of the story and multiplayer aspects.

I also feel it would be better to fix any bugs that pop up on other systems earlier than later, so please report any bugs you find. The rats do enjoy eating bugs. ”

Approximately how long will this game be in Early Access?

“Sewer rat will likely be in early access for years. There is a lot of features I plan to implement and I'm not sure if I will ever really feel done with it.”

How is the full version planned to differ from the Early Access version?

“***massive spoiler*** Don't read this if you don't want to know yet. Sewer Rat takes place in a post apocalyptic world. How that world shapes up will be revealed over time. You are a rat rebuilding a society fit for rats. The full version will have much more of this concept in it. ”

What is the current state of the Early Access version?

“In the current alpha build:

You can explore a lite version of what the seed based story/server worlds will be like (none of the actual story is in this build yet). Go solo or adventure with a group of friends via split screen. You can always make some new friends in game with the companion system. If you see a wild rat, just slow down and start squeaking at them. I'm sure they would love to join your mischief!

Walk, run, climb and swim anywhere you want. You basically have infinite stamina and can hold your breath for up to 3 minutes (like a real rat!).

Eat to survive! Rats are mesopredators, so beyond the stereotypical concept of foraging, you can also hunt for your food.

Start building your first nest! It's really fun and you might even find some unique and interesting items for your nest. Some items are rarer than others. When you're done building you can take a cozy nap in your nest.

Learn how to play the game and explore the controls in tutorial mode. Your instructor is none other than Cherry aka the legendary Kiwi Mouse! She will help you become a better rat and give you certificates that prove just how rat you are.

In arcade mode, you can race to get food, play a game of tag, or get into the competitive world of ultimate pea fishing. If you don't have friends to play with you don't worry, there are rat bots ready to join you.

There is also a built in camera system to take awesome pics of rats! ”

Will the game be priced differently during and after Early Access?

“The price of the game will gradually rise as I land milestones. I have a lot planned for Sewer Rat and I want to see it become it's full self. ”

How are you planning on involving the Community in your development process?

“I would love to listen to feature suggestions and feedback! Not all will fit in with what I'm planning unfortunately, but I genuinely want to make sure this game scratches your rat itch. It's very species affirming for myself but would love to make it that for you too. Also please let me know about any bugs. ”

About This Game

Currently in Alpha!

Go explore the world as a rat and bring your friends along with you! Sewer Rat is a split screen multiplayer game about being a rat. Not in the stereotypical ways a human would think of them either. I created this game from a rat's perspective. 

In the current build, you can explore a lite version of what the worlds will look like, play against/with each other or bots in the arcade, build nests, hunt and learn how to rat in the tutorial section. While I think it's best experienced with friends, you can absolutely enjoy it solo. There is a companion system in the game that allows you to recruit up to 5 rats to bring along with you!
