In fact, the system requirements are low. An advantage of this approach is that it is likely to run on most systems.
Graphically speaking the game employs a much older looking aesthetic than most games. There is an item shop where players can purchase power-ups and support items. But for the special zombie modes, there are more creative and off-the-wall weapons available that have no bearing on reality. Most of the weapons in CS N:Z are based on real-world examples. Low-level materials can be upgraded through a synthesis system, giving players another option in terms of upgrading their arsenal. Most of the materials needed for in-game crafting in Counter-Strike Nexon: Zombies comes from the gameplay itself.
The crafting system is typical of massively multiplayer online role-playing games in that you typically need a design and a set of materials to craft an item.
