I did try Lost Alpha, multiple release versions, multiple time and I’m sad to say that it’s not good. The head head honcho of the dez0wave team, dezodor, said that everyone in the team that worked on the game, wanted to put their own ideas into it. Some wanted to keep it close to SoC where it was mostly exploration with combat sprinkled here and there and some wanted it to be a full action packed game like CS.
They also bit more than they could chew when they decided to include in-game cutscenes, especially since they didn’t have a decent animator for most of development. You can see some of the abomination in this video
The original releases were filled with trash like these but most got removed in the Director’s Cut.
As for the worst offender of them all, the game was straight up broken. From the version that got leaked all the way to the last version before DC got released, it was a miracle if you could play the game more than 10 minutes without crashing, let alone finish the game.
In the end, dezodor outsourced the development of the DC version to the Russian community of the game and they tried their best to fix it. There are even repackages of the DC + community fixes and enhances but it’s still fundamentally flawed, with some serious issues still in there so I say skip it.
Fun fact, dezodor actually had talks with owner of GSC, Sergiy, to have the game part of the main series and actually sell it commercially but the leak happened and the plans got scrapped. Really wish it had ended up as good as Black Mesa
