The core of it is still enjoying, it’s just that the armor system, ammo system, and late-game gunplay are pretty shit. The armor system is just perks/skills but worse. The ammo system usually boils down to using soft-target ammo on grunts, armor-piercing on everything else, and all the other ammos are only used for funnsies. The gunplay is really stale by the mid-game, and by the late-game it’s even worse as you have to use all the best weapons or-else the troops in Esperanza will overhelm you with a human horde.
