Jack dies in 1 bullet and has to hide, so basically one of your friends can’t play unless you count, “hiding and giving ammo” playing. $70… for that?
The units simply have MORE heath and MORE damage, the difficulty doesn’t change. So you just spend hours in cover shooting when enemies are reloading. There are ways to make a game harder and keep it fun, look at halo legendary. More elites, smart AI etc.
Gears 5 has one of the worst insane campaigns I have played of all the gears games.
Like @Circa_Darkrage said–Gears 3 was the worst Insane mode. In my experience ammo was scarce and we had to count our shots until we finally gave up in Act 4. However, after spending most of this afternoon on just the end of Act 2, I’d say Gears 5 Insane is as brutal, if not worse than Gears 3.
