We create the most advanced multiplayer modifications for AAA games. Our portfolio includes multiplayers modifications for Grand Theft Auto V ©, Grand Theft Auto IV ©, Mafia 2 © and Just Cause 3 ©.

With NANOS MULTIPLAYER FRAMEWORK we provide core components for multiplayer development so you can focus on the important part of your project - the game.

Who are we?

nanos is a team of young, ambitious people from different disciplines, in particular various fields in computer science, business administration and law, which are convinced that the success of upcoming video games is measured above all by the multiplayer and coop experience.

This includes the possibility to be able to modify the game players imagine. People don’t want to play their games alone at all, they want to share the experience and go through feelings with friends together.

nanos pursues this concept since it's been found in 2011 and will provide the possibility for all developers to achieve this goal amongst others with an all-in-one framework, whether othe developer is a established organisation or an indie-studio.

Our vision is to set new benchmarks in multiplayer experience and to make community’s imaginations possible to influence the game in a way game developers never had an eye on.
