XBill

XBill is a pretty simple arcade mostly written in C++ during the summer of 1994 by Brian Wellington and Matias Duarte of Psychosoft.

With version 2, the game has been rewritten in C.

The latest version of the game is 2.1. A version was included on the 100 Great Games for Linux shovelware collection.

Gameplay
The player is a sysadmin that has to stop little people trying to infect the machines on your network with a virus called “Wingdows [TM]”.
