This is utter nonsense as I said. Your firepower does not increase linearly with your level. Because of the gating, there are thresholds you cross (level 20, 30, 40 etc) where you blast forward in firepower. Leveling up as fast as possible and using the new toys and perks that each level brings is far more efficient than trying to level slowing to keep your gamestage down. I am level 95 now, and the game is now SUPER easy.. Day 21 horde came and the base (Steel) took almost zero damage, it was totally easy (difficulty 3, gamestage = 139). In short, if you want to dominate the game, level as quickly as possible.I agree with Roland in that if you 'level up quickly' you've got to own up to the fact that you'll get the 'hard core zeds' after you as I've experienced first hand!
You realize this was nothing whatsoever to do with your gamestage? Well not directly anyways. I suggest you research how the game determines the wandering horde types it is going to spawn for you. (hint: it's random)Within about 15 IRL minutes I got two wandering hordes of 20 zeds or more a piece. Then much later, the next day right before I got to the traitor to get my reward a pack of +10 zed dogs?!?
