Early game, 10/10. Mid game, 6/10. Late game, 2/10.
Early game is always fun and exciting, making risky plays to take out the ducans and what not, but around the middle of the mountain, the game gets way too easy with the right guns. I flew through hard mode and rebel 1 like nothing using only 4 guns, all primaries. The bosses are way too easy, predictable and have way too little moving space and attacks, I killed bosses for the first time as if it were the thousandth time. Lastly "rare" and "uncommon" resources are too finite, I'd like to farm max tier guns without having to wait 12 hours until the next shop or patrol has what I need. Unless you use the super resource bug from bosses, your probably never gonna have more than 3 maxed guns for a few months.
