It was ported to the PC in 2002 by devpack who released the code in 2011 on github and google code which is where I picked it up and ported it to the Raspberry Pi.
This is the port, but check out the original Amiga game.
I got some help from the Raspberry Pi forums in getting it to compile then it was case of sorting out a few case sensitive filename bugs (it was original written for Windows!) and tracking down a bug in the original code which was causing a memory access error and segmentation fault.
The code is on github.com/martinohanlon/mayhem-pi.
sudo apt-get install liballegro4.4 liballegro4-dev git clone https://github.com/martinohanlon/mayhem-pi
cd mayhem-pi ./start
Player 1 - z, x, c, v, g
Player 2 - left, right, pad del, pad 0, pad enter
Player 3 - b, n, 'comma', m, l
Player 4 - y, u, o, i, 0
Change level - 1, 2, 3
If you want to modify the game, I've got a couple of things on my list, you can recompile it with.
cd mayhem-pi make
