My experience with Mapping and Modding
I mainly map for the game "Portal" and I am pretty well experienced with modding, just haven't released one yet. I developing a Portal mod that will remain a secret for now.
Am I good with Hammer Editor and/or Modding?
I'm pretty well experienced, I still learn some around every 2-3 days but nothing major.
I can make some very nice Portal maps, right now my Portal mod is a bit bland since I haven't added a GLaDOS voice yet.
Funny thing, my mom can make a very good GlaDOS Voice which I obviously edit using melodyne or something like that and so I will have her as my voice actor.
