Cellular Conquest was a game I built for a friend's Connecticut Science Center exhibit from July-August, 2015. The point of the game was to serve as a very simple demonstration of a cell's defense system, particularly antibodies and proteasomes. It was intended to be played in a touchscreen (read: tablet/laptop) environment by all audiences.
NOTE: This is a very barebones tech demo and by no means a final version. It was also my first attempt at using
pygame, so there are likely lots of things I'm doing wrong. There are plenty of minor bugs, but nothing to render the game unplayable. The code is open sourced for both historical purposes but also to show how a beginner can approach
pygameand develop something more sophisticated than demo code.
How To Play
- For OS X Homebrew users:
brew install pygame
- Comes preinstalled on most Linux / OS X versions
In a console:
The default game resolution is
1280x800. Depending on your screen resolution, you may need to change this. You can do so like this:
python main.py 500 800
This will launch the game using a
NOTE: I realize now that resolution is probably the wrong term (should be window size), but that's what I called it when I wrote the code so I'll keep this here for clarity's sake.
Here's a screenshot:
The main goal of the game is to protect your cell from viruses. Viruses will continually spawn at random positions off the screen and head directly for your nucleus. If any virus manages to touch it, you will lose the game.
One way to prevent this is by placing down antibodies outside of the cell. You can do this by simply clicking/tapping outside of the cell. Antibodies can't move, but they will slow down any virus that hits them. When a virus hits an antibody, it will be tagged. Tagging a virus will consume the antibody, but you have unlimited antibodies, so you just have to make sure you keep placing them down.
NOTE: You don't necessarily have to tag viruses. It's just a good idea to help prevent any viruses from catching you off guard.
When the game starts, you will be given three proteasomes to command. If a virus touches a proteasome, it will be destroyed. To select a proteasome, simply tap/click on it. The proteasome graphic will change to . Then, tap on a different location. The proteasome will begin moving to that position and stop once it reaches it. Note that a proteasome is an internal part of the cell, and therefore it cannot move past the cell's wall. You will have to be strategic with your movements!
You can't! In real life, the cellular conquest never ends :)
When you lose, the game will tell you how many seconds you lasted, so if you want you can try to beat your previous record.
The original version of Cellular Conquest used random graphics taken from Google Images. Obviously, those aren't really distributable, so I got my good friend
Andrew Abosh to recreate them. The images you see in the
res folder were all made by him. Thanks, Andrew!
This project was left alone once it fulfilled its purpose as a tech demo. That being said, there are plenty of ideas that could be implemented, and many bugs that can be squashed.
- Customizable amount of proteasomes
- Limited antibodies
- Difficult selector which modifies entity speeds
- Automatic resolution picker
- Polished start and end screens
- Multiple lives
- DOCUMENTATION! A lot of the code (especially that in
BaseClasses.py) served more as a framework to extend
pygamerather than game-specific logic. If documented, it could maybe help out others struggling to implement functionality
No idea what this is.

Support for this will be removed in a future release. Also, this makes the host incompatible with version 3 audio units. Please transition to the API's in AudioComponent.h.
Sometimes, when you tell a proteasome to move somewhere, it will get deselected but won't move to the desired location.
In addition, proteasomes can sometimes freak out once they reached their location and repeatedly move back-and-forth in place. This is likely caused by the navigation code failing to detect that the proteasome has reached its location.
When you close the window, weird graphical artifacts appear in the window for a few milliseconds until the window finally closes. While not a big deal, this might be indicative of a larger problem (such as objects failing to be de-initialized, which can lead to memory overflows).
Probably some other stuff I missed.
