Highly recommended. This game is awesome. I bought it when it came out. The improvements they made to Xen over the original are incredible. If you enjoyed HL then playing this will be like you remember but better in every way.
At -80% the game is an OK buy but development is dead. Don't expect it to ever play well on Steam Deck, if you care about that. They only push their merch store now.
The recent anniversary update to the original HL1 makes that an appealing proposal.
I'm aware of workarounds for the glitches but the fact remains that Crowbar Collective doesn't work on Black Mesa any longer, we don't even know if actual developers are still there, so they aren't the ones making any fixes. They just collect the money from game sales als the merch shop.
