Well after 3 long years, I finally did it. I finished the whole Quake 2 on CooD...
But it was really weird. I felt like the whole game was bugged, hope it wasn't and I finished it legally.

I've never had critic moments, some of them were fun xD.
Didn't find too much secrets because I did not want to . But I think I found most of them ;p. Sometimes I did very good and fast run (not killing too much) and sometimes just carefully going through levels.

Hope I will finally earn my solo star
If you want I can get some screenshots but they aren't any special.

Congatulations on your victory!
if you have pics of the final lever you can show those.
you said the game felt somehow bugged? i remember having a odd problem with some engine that causes monsters not to see me if i dont shoot them (no notarget on).

Sometimes I had something like this too, but I shot monster, he ran away and stand still... lol. Gonna upload pics later.

Congratulations bcK !!
