Overkill 2 is a game that, despite being on the iPhone, iPad and Google Play, will appeal to fans of old school arcade shooters and new school shooters alike. In Overkill 2, there are two forms of currency. One of them is coins, which are fairly common, and which will buy you most of what you need, but there are just never enough coins to go around. Medals are the rarer of the two currencies. They’re not easy to get, but they will buy you the absolute best weapons, armor and power ups that you can find. Read on to find out how to get both for free!
Obviously, you can get a bunch of coins just by playing stages over and over. You can go back and play against waves that you have already completed, but a better bet is to play against the toughest waves that you can.
You have three missions at a time, so work on completing the missions, because they are the most basic way to earn free coins and medals. Not all of them will earn both, but all of them will earn you either or.
You also earn a good sized coin bonus for completing a wave. The higher the wave that you complete, the higher the bonus. A free bonus of 5 medals is earned each time that you gain a rank/experience level, as well.

You can earn 2,000 free coins if you log into Facebook from the game. Also, each time that you complete a gun collection (three guns that are in the same collection), you’ll earn a huge coin bonus and a sizeable medals bonus. There are 9 different collections in all.
Lastly, you can go to the medal store from the main menu, and you can get to the Tapjoy offer wall, and complete all kinds of offers which will earn you free medals. Most of the offers are free, while some of them require you to pay. Additionally, if you go to the Tapjoy website and check out the offers on the site for Overkill 2, there will be even more offers that they can’t show on the app – offers which involve you downloading and running another app in exchange for free medals, which are the easiest offers to complete out of any of them.
