“Playing Half-Life: Blue Shift after Half-Life and Opposing Force was fun. I liked seeing the Black Mesa incident from the perspective of a security guard. The story was interesting and it was cool to explore other parts…”
“Honestly better than what I was expecting from what I heard. Definitely the weakest of the OG trio but far from a bad time. Biggest crime is spots do feel a bit more lackluster and sometimes you are expected to wait for…”
“Unlike opposing force, this one feels like a slightly more interesting "DLC" although it's very short. It's only worth playing if you care about the story, not that there's much more to show over the base game. I can…”

“underrated as hell but seriously has the most broken ending and beginning of all the three hl trilogy titles. it's really unfortunate that valve never updated these to fix the things hl1 received. a big example of this…”

“Super short, but a good time! I've never played the original Half Life titles so this was my first experience and it seriously still holds up all these years later. It's also nice to get some backstory for the GOAT…”

“SHORT, CONCISE AND GREAT BUY IT ON SALE!”
“A microcosm of the original [i]Half-Life[/i]'s gameplay with the best take of the alien borderworld outside of the fan-made [i]Black Mesa[/i]. The game stays exactly as long as it should.”
“A quicker, darker (literally have to use your flash light more often), more claustrophobic Half-Life 1 experience through the eyes of a legend of a Black Mesa security guard.”

“Half-Life: Blue shift is the second DLC for the original Half-Life, it was released in 2001 and developed by gearbox interactive and published by Valve. It offers a different perspective to the Black Mesa incident,…”

“This DLC does not introduce any new gameplay elements nor does it fully utilize the existing ones. It has less enemy variety, weapon variety and jokes. It's just a straightforward and boring story built entirely out of…”
“The base game was really fun, but this add-on just feels like a cheap way to capitalize on a great game. Unlike the base game, enemies here feel randomly copy-pasted without any sense of progression. The areas you…”
“Nowhere near as good as the original half-life, my favorite game of all time, but it's a pretty neat expansion for it.”

“eh, if it's on sale maybe but it's kind of bland, really slow and the latter half is a slog. feels longer than it is, not in a good way, doesn't really add anything to HL”

“half life done overboard, i like it but dont play onm hard for your own sake”
“Really fun game. Quiet short campaign, no new weapons like in Opposing Force, but I think it's okay if I had a lot of fun playing this game. Also this is the most easiest and "simpler" Half Life game. I know this game…”

“You can finish it in under 3 hours. Cool to see another side story for the first Half-Life. But it's much worse than Opposing-Force. Blue Shift is nothing "new". Same weapons, characters, enemies. Feels a little cheap”

— a player, Steam review · 3 hrs played“This expansion is like the opposite of Opposing Force, in that it is kinda bland. The arsenal is limited and the difficulty has been tuned down. The main appeal of this expansion is seeing how Barney got out of Black Mesa, so I do think it is worth at least one playthrough if…”
— a player, Steam review · 3 hrs played“it's alright, i liked it, worst of the expansions that's for sure, gameplay is a lot slower, no new weapons, too many puzzles which some of just make no sense, also like half of the game you were just running around with a scientist and the ending was really abrupt”
