NOTE:i didn't created this video.have you ever heard of a program called garry's mod well using this program you can control every hl2(half life 2) unit as ragdoll and you can do everything you want spawn hl2 props,npcs and etc.
P.S.you can buy this program in steam website and only if you have hl2 full verson.If you already knew about this program then why were u even reading the explanation about this program.And by the way there is some TF2(Team Fortress 2) units.This video is an example for what kinda needs u can use that program.You can buy it in here or you can get an illegal version in well this time im not telling you where to get an illegal version try look for Gmod torrents in the internet maybe youll find something...
P.S.:the legal gmod version requires these games :
Half-Life 2,Half-Life 2 Deathmatch and Counter Strike Source
AND THE ILLEGAL VERSION DOES NOT REQUIRE HL2,HL2:DM AND CSS.BUT WITH OUT THE GAMES I SPECIFIED THE ILLEGAL GMOD WONT BE ABLE TO FIND ITS CONTENT.
