Blue Shift, a 2001 "Add On" to Half-Life 1, has you return to Black Mesa as security guard Barney Calhoun. The gameplay is honestly much of the same though I think the three years between this and the first did add a bit of polish. The inclusion of platforming was fun! Wish I was better at it lol. The fact that you only see Gordon like three times in this does make me laugh when you get to HL2 and Barney tries to play off being his best friend. He's southern and cute though, I'd let him be my best friend. https://store.steampowered.com/app/13...
