I am new to this game and been playing for a week and already reached gear hub 4 and have Stalker and arachnes, I wanted to buy revokers and storm rack since I've died by mech using them but both combined cost 1,275,000 credits. I want to farm faster for them but idk how to farm quickly and the tournament I always get has someone who legendary mechs and 6000 squad power and I can reach 1st place. So any alternative ways other than promo codes?
