Ok, ALIEN: Isolation is amazing and by far my favorite Alien related game by far. To me this game is as close to flawless as it comes, but even so I have a few minor things that bug me and that I wished they would've done differently.
I'm not a gun guy by any means, but it kind of annoys me that added new guns to the game when there already are a bunch of equivalent pieces of weaponry they could've picked from the movies (ALIEN).
For example, they could've gone with the original
"Laser" Pistol (Kane carries it in the Derelict) instead of the Revolver we see in the game:
The Laser Pistol (or whatever it is) could take just same amount of time to recharge and could have the same rate of fire and amount of ammo before reloading it as the Revolver. Same function but a design and lore more true to canon.
...Or why not Ripley's
Speargun instead of the weird Bolt Gun they implemented?
The Speargun is a single-fire weapon that takes time to reload. Just like with the Laser Pistol/Revolver, they could just switch the designs to make it fit, but they could also utilize the fact that the Speargun is a harpoon weapon, as seen in the movie. Wouldn't it be cool to temporarily shackle an Android, or even the Alien, for a few seconds, giving you some precious extra time to escape or whatever.
I also wish that they would've been more frank with the Egg-Morphing concept rather than just hinting at it. It's so gruesome and nightmarish and would've really given the game another dimension of horror to it.
Another thing that I wish they would've had time to implement in the game is to pushing furniture around, toppling over chairs or even throw them to divert attention. Pushing furniture would enable you to make your own makeshift barricades, or just temporarilly blocking doors. Lighting them on fire to create a temporary barrier between you and your enemy would've been amazing too.
Really hope there will be a sequel!
