Thank you for sharing this great vid!
I didn't watch all of it, since I intent a full retrospective of almost Alien games myself, and I don't want to spoil this future experience... But I looked from 8:23 out of curiosity and saw the full review for Alien 3: The Gun, which looks like an AMAZING arcade game.
Honestly, the production value and general atmosphere of this work are OUT OF THIS WORLD.
Besides the fact the game features an apparently infinite number of enemies, the general vibe of the series and of this specific movie have been very well understood. The camera moves are great, the spritework is STELLAR, and like the Youtuber, GManLives, says, the visual feedback when you shoot enemies, the environmen and corpses is unique. What a nice surprise.
