Almost everything, from the game's UI to some of the weapons' behavior, seems to be directly inspired by Valve's Counter-Strike series.
It's clear from the start just what type of game Sudden Attack seems to be emulating. Featuring a tried-and-true approach to the online FPS genre, Sudden Attack offers more than meets the eye for new and veteran players. What have we been missing by playing other titles instead of Sudden Attack, then? A solid, outstandingly dynamic cooperative shooter. With massive popularity in both Korea and China, Sudden Attack emerges as an alternative to other big-name shooters that might be more popular with Western audiences. Sudden Attack could easily be called one of Asia's most popular online FPS games in more than a decade, and with good reason.
