FormulaOne is a wargame that has been rescued from the demise of intruded.net, previously hosted on formulaone.intruded.net.
FormulaOne’s levels are called formulaone0, formulaone1, … etc. and can be accessed on formulaone.labs.overthewire.org through SSH on port 2232.
Data for the levels can be found in /formulaone/.
The source code for the first level can be accessed by logging in to a wargame hosted on the same server. Your first task is figuring out which wargame that is.
