My bro
He has 7 years
He practically watched every move i made in hammer since i installed it.
I didn't teach him anything he just watched me and started mapping.
He knows how to use some entetys like prop_static , prop_physic then npc and stuff also knows how to use displacement.
He also knows how to copy/paste in hammer (f*ck) >_>
I compile maps for him because hes a big bot
I must say i'm really proud.
Here's his new map unfinished :lol
