Sure, you could probably jailbreak your iPhone, iPad, or whatever and download a hacked up version of MetalStorm – but where’s the fun in that?
Here are some quick ways to get more blue coins without spending money out of you own pocket:
Watch the ads
The pop-up ads in Metalstorm give you 1 blue credit to watch their 30-40 seconds ads. Sometimes they play more often, letting you rack up some blue coins!
Earn Free Coins
In the blue coin menu, there is a button in the bottom corner to “Earn Free Coins”. Sometimes you can gain 200-500 blue coins by simply signing up for emails or filling out surveys.
Start playing the game!
You will gain skill and blue coins and credits if you play the game. Sure it is hard to beat somebody with a fixed up plane, but at least you will eventually gain skill and more blue coins to customize your plane or get a new airplane all together.
Play Survival Mode
Same with playing the game in versus mode, but you will not have to fight people with fully customized planes strapped with Bisnos! Survival mode is definitely where beginners should start the game. You can even play in co-op mode to get to higher levels with a friend helping you out. Survival mode is the fastest way to get skill points by playing the game.
Play missions to gain points and increase your skill level. Make sure you make some friends in the game to be able to add the as a wingman. You also get to unlock some airplanes by beating the campaign missions. Campaign mode in Metalstorm also awards you with missiles and cannons, as well as a nice chunk of green credits.
