Hello! Take into account that you are able to take part in the Events (both in-game and Community ones), complete Objectives and Achievements, join Tournaments, move through the Progress Path, and stuff! Besides, there are always affordable Offers, and Mech Arena Store https://store.plarium.com/en/mech-arena/ 🛒

With low effort, and without spending real money, you can earn the following:

1. From daily objectives - 10 acoins, 7,000 credits (10k if you get ads), one gold crate, 500 XP

2. From weekly objectives (every 4-5 days) - 200 acoins, 12,000 credits, 3 fortune keys, mod parts

3. In each tournament - 

  a. Almost zero effort - come last in novice mode every day, get 12 fortune keys total

  b. Very small effort - get positions 7-15 every day, get 12-18 fortune keys total, roughly 20,000 credits.

  c. Slightly more effort - try to get position 6 or higher on some days to get some acoins and more credits.

Over a month, playing just a handful of games a day, this gives you a minimum of 1500 acoins, 300,000 credits, and 60-90 fortune keys. Use the fortune keys to open the 10-key vaults to maximize your chances of getting either credits or acoins.

This doesn't account for other events that keep popping up, the monthly battle pass, progress rewards, gold and silver crates from victory and combat points, hangar showdown, etc. So actual earnings will be more than what I've mentioned.

Hey, you just described my routine lol.

Dont open all crates and claim all event rewards. Use them for the daily blueprint task. 

Also, spending 2k credits in store helps with getting a-coins faster. 

For fortune vaults, only open the 5s till there are about 10-14 skins left in the 5 crates. Then open the 10s. It helps with a-coins and credits.

 Idk if this is true, every time I spend a-coins and then open a vault, I tend to get 750 a-coins more often. Again, this may or may not be true
