project

I have recently been assigned a project to further develop an existing code base. The code doesn't contain any tests and not even one single line of comments. The whole "thing" is written in a really obfuscating manner so it takes a lot of time to figure out what happens.

How do you usually approach this kind of problem? Tips and trix on how to handle this situation?
