The Intergalactic Research Network is a new addition to OGame.
It was added on the 3rd of August, 2005. This new technology allows you to link your Research Labs together to improve research times.
With zero levels of Intergalactic Research Network, you only get the benefit from one Research Lab. With a Level 1 Intergalactic Research Network, you will link the two highest research labs. Each extra level of Intergalactic Research Network adds another Research Lab to the network.
Example: I have a level 12 Research Lab on my “research planet”, and a Level 8 Research Lab on my home planet. Once I complete the research for the Intergalactic Research Network, I will have the equivalent of a Level 20 Research Lab. If I build a Research Lab to level 10 (on yet a third planet), then get Level 2 Intergalactic Research Network; I will have a Level 28 Research Lab when I do my research.
You only need to store resources on one planet, since that is where the resources are used.
The additional Research Labs do not require any resources for them to work. They just contribute “brain power”.
If research is important to you, then you should research several levels of Intergalactic Research Network, and get several Research Labs to Level 10 or higher.
If you have a Level 8 and a Level 10 Research Lab and Intergalactic Research Network Level 1, you still cannot research Graviton. You need a lab that is the proper level for what you want to research. Having an IRN just lets you research technologies faster.
