Banking

This tactic allows you to get the most for your dollar by investing your money early on in a game in as many things as you can build. In multiplayer games there is a constant 25 RU injection given to you if your total RUs are less than 400. Every 15 seconds you get 25 RUs to build with. While this doesn't sound like that much it does add up. An extra 100 RUs per minute to spend on extra ships can make or break your game.

Considering that there is usually a 5-10 minute wait from map start to the first battle an extra 300-400 RUs can give you the edge you need, whether it is an extra support frigate or a few extra corvettes or fighters. Even if the RUs are just used to get you past a build pause the minimal amount of micromanaging it requires is WELL worth the effort to keep your builds running like a well oiled machine .

Some good ships for RU banking:

So when ever your total RUs are about to be depleted you can go into your build manager and cancel one of the 'investments' to keep it from bottoming out. Keep in mind though that you want to keep your total RUs BELOW 400 when canceling a build so cancel the appropriate amount for the situation to keep that money rolling in.
