After playing Endless War 5 I went for this one, some changes that were pretty good such as Air Support and being able to go over debris. But HO-LY that Tiger tank spam on later levels. Worse part is that the "cannon tree" (part of the upgrades that are focused on damage, piercing, range, etc.) has better bonuses than 5, but it really doesn't feel like you are actually getting better because the Tiger II specially is such a bullet sponge that is unbelievable. The AT shells/Howitzer shells hybrid tanks is a very nice mechanic, but the more I got close to the end the more it got overshadowed by the fact that I had to destroy +5 tanks that needed 4 of the Howitzer shells to die, and I have Pierce and Damage on max. The game itself isn't bad, classic Endless War, but it can get tiring pretty quickly with spongy Tigers that also slap back quite hard.
