Hi, I'm looking to see if anyone has a save with all the Exo Survival mode maps unlocked. I'd like to get my last achievement, which is the zombies round on the Tier 4 map. But to do that, I'll have to beat 50 rounds of Tier 1, 75 rounds of Tier 2 and 100 rounds of Tier 3 maps, which will be a huge grind. I have unlocked Tier 2 maps now, but I'll still have to beat 175 rounds, which will take many hours. Any help would be greatly appreciated. Thank you.
