Best upgrades to get?

What are the best upgrades to save up for.

First get basic upgrades like General: Infantry attack, General: stack defence, etc. When you're around rank 5 and got SM or a good strat, then try to get Faster Infantry it's basically the best upgrade in the game with Expendable Infantry. Don't buy upgrades like Faster Marines or stealth upgrades if you won't use them. Infantries are the main unit with almost every strat so infantry upgrades are the best imo.

Ok

According to Desu best upgrades to get are:

• Cheaper Infantry.
  
• AirTransport Capacity II (after getting the first one obvs).
  
• Faster Infantry.
  

He suggests this if you want to be a competitive player, and I approve. Also I suggest not making a clan after you got the main upgrades. If you make a clan before, you waste 10k SP , when you could of used it to get important upgrades . Make a good decision!

BTW - It's always good to decide what style you play before choosing what upgrades to get.

At your level, I suggest saving up for the different strategies, and deciding how you would like to play afterwind Once you decided on your main strategy, focus on upgrades that would boost your gameplay with that strategy.
