The first priority is the game itself. This includes balancing the core game loop together with the overall experience of in-game progression. And community feedback is of vital importance regarding these. Later, after we’ve achieved this balance, monetization will be added in the form that won't provide any unfair advantage over other players.
Everything will be achievable via gameplay (except for Founder's Pack exclusive items). In other words, players will be able to buy certain customizations and in-game Boosters. Boosters will come in many shapes and sizes from increasing the amount of loot to boosting the quality of airdrop Crate.
