Half life 2, everything after nova prospekt and before the citadel
I booted the game up the other day and was at that section, could only move forward a map or 2 before I started dying and dying and dying, couldn't tell where I was being shot from, was fumbling my weapon switching, couldn't aim for shit
I feel like an old man when I play fps games, they're just not for me, but damn I like everything else about hl2. No wonder I loved infra so much
