I enjoyed Horde mode in Gears 2 and playing through the first couple of campaigns in co-op back in the day but those games did not age well. They're ugly and bland looking, the enemies are all bullet sponges and the focus on shooting from cover completely stopped any momentum the game would build up. It was just move 25 ft., sit behind a wall and shoot for 5 minutes, move 25 ft. etc. Shit's boring.
I might get the new remaster just to play co-op again with buddies but I'm absolutely not paying $40 for that shit.
