Zombies 2

Rus/Ruslan is a Kazakh-looking guy. He's a bit dim-witted, but cool. Sometimes he doesn't understand jokes and innuendos.

Mara is a smart guy, but not a nerd. He is of Asian appearance. He doesn't smoke or drink (but that will change soon). He is the tallest and the smartest.

Tilya is a guy of Ukrainian appearance. He's a bit of a boor, often makes jokes, wears Adidas, and laughs at Tima's jokes. Tima is Tilya's best friend. They both make fun of Mara and Rus.

Tima is a Kazakh-looking guy, a "kid from the hood." He makes vulgar jokes and, along with Tilya, constantly makes fun of Mara and Rus.
He wears Adidas and has a slightly boorish manner of speech, but he makes vulgar jokes with the ladies.
