Doom (activity)
Doom is a terrifying, bloodthirsty game involving running around dungeons and shooting at monsters. It is probably not for young children, but is great fun for older ones.
[Freedoom] is a free software clone of Doom, based on improvements made to Doom's 3d engine with new maps and monsters.

How to install
The following instructions need to be run from the Terminal activity. You will need a working internet connection on your OLPC for the install only. The instructions worked on a B4 OLPC laptop running Build 650.
- Open the terminal
- Switch to the root user, by typing:
su -
...and entering the root password, if requested to.
- Then type
yum install prboom
- The download is about 18MB, so will take a few minutes.
- When you get a prompt again, type:
exit
- To run Doom, type
prboom
Changing Doom to run in full screen mode
To run in full screen mode, type:
prboom -geom 1200x900
To permanently adjust Freedoom to run in full screen mode all the time, type:
cd /home/olpc/.prboom nano prboom.cfg
This will open the freedoom configuration file in the nano text editor. Find the two lines in the file with the words:
width 640 height 480
And change them to:
width 1200 height 900
Then type ctrl-x to exit, and type y to save your changes. Now, Freeoom should run in full screen mode when you type
prboom
