Basic guide with tips before you play Half-Life: Alyx.
There is just 1 big spoiler for those that have not played Half-Life 2: Episode 2, at the very start.
The intro is Alyx on a balcony and immediately there is a text in front of you saying "5 years before spoiler", just close your eyes when you enter (this shows for like 5 to 10 sec).
The rest are small spoilers, you will miss them if you don't really know it.
You have some "Armor" that you can equip that protect you 1 time from headcrabs and barnacle (the tentical thing against the ceiling), it's not highlighted or anything, try to put stuff/helms on your head and see what stays.
The shotgun can hold 7 shells, not just 2, so pump that bad boy full. But be carefull, shotgun ammo is hard to find (you rarely find it and it's kind of not so obvious like the other pickups).
You can store items in both wrists (so 2 item storages) and you can store ammo and resin above either shoulders (see what is easy for you).
Just a tip, but if you got trouble with aiming, get a laser attachment, it becomes 100% easier with it.
Your hitbox is your hands, head and everything between that, so make sure to crouch or lean over with combat.
If you hit a dead end from the main path, high chance there is something in that room, can be ammo, items or a resin.
