Buy Aegis of Earth: Protonovus Assault Steam Key

Q: Why is the Steam Key of Aegis of Earth: Protonovus Assault safer than the account format?

The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Aegis of Earth: Protonovus Assault to your game library. The account format requires more complicated steps and is more prone to errors during activation.

How much does Aegis of Earth: Protonovus Assault for PC cost right now?

Aegis of Earth: Protonovus Assault for PC starts at €2.30 at Kinguin, a Steam key.

That €2.30 already includes the AUGGOC10 coupon, so apply it at checkout or the store will show you a higher price.

Only 6 offers across 6 stores carry it, and thin supply means the price barely moves.

Is it worth buying the Steam Key for Aegis of Earth: Protonovus Assault now or waiting?

That €2.30 key is at its usual price: no bargain, no spike.

Those €2.30 are 12% above what it usually costs, measured on the store price.

Not counting today, 1,496 days out of the 1,882 days on record were this cheap or cheaper; the lowest it has ever cost is €1.08.

It is not a bad price, but it is not this Steam Key's floor either. If you are in no rush, we will tell you the day it drops.

Worked out from 2,792 daily records of the Steam Key for Aegis of Earth: Protonovus Assault across 9 stores. See the full price history.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.

Can you activate Aegis of Earth: Protonovus Assault in US?

All 6 offers are Global, so the code redeems on any account no matter where it was created.

Is Aegis of Earth: Protonovus Assault worth it?

Why is there such an expensive Aegis of Earth: Protonovus Assault offer?

One listing is worth ignoring: the Steam key that Greenmangaming has at €19.99 is more than 8 times the cheapest offer and is not what this game costs. The number to work from is €2.30 at Kinguin.
