Hey, guys. Welcome to CS:GO community. Danny Trejo, a super star from Hollywood, seminudely advertised CS:GO weapon skins called Cutthroat Collection from filmaker Chris "C-LegFX" Le. All the weapons in Cutthroat Collection are based around B movie guns, including sawed off shotgun, M249, Desert Eagle, dual Berettas, Tec-9 and the R8 revolver.
As you know, players can submit their self-make weapon skins to game developer Valve. Only the weapon skins get enough upvotes, can they be used in CS:GO. Therefore, Chris "C-LegFX" Le asked Danny Trejo to promote his weapon skins. Danny Trejo just starred in Juarez 2045 which was directed by Chris Le. I bet they have good relationship. In addition to making CS:GO weapon skins, Chris Le also made skins in Dota 2.
