Take your time with it, don't rush it, brilliant game.
I think this also highlights what's wrong with a lot of modern games too, it's a full on experience, no boring travelling to & from location, it just grabs & holds your attention for the duration.
Never has searching through filing cabinets looking for additional resin been so much fun!
I discovered today that you can effectively hold the pistol in a 2 handed manner, makes aiming so much more accurate.
Not sure how much VR you have played but there are some other games out there that you should try.
Skyrim VR fully modded: is a truely awesome experience.
If you like the Fallout series of games, Fallout 4 VR is really good.
Alien Isolation with the Mothermod: You want the bejaysus scared out of you? Extremely tense game.
Robo Recall: A really good VR game. So well done and so much fun.
Lone Echo 1 and 2: Makes you feel like you are there, for real.
Walking Dead Saints and Sinner: Great Zombie killing VR action with decent story.
Moss: A real gem of a game. So often overlooked.
Asgard's Wrath: Lots to do, Intense combat, Thowing Axes, bows and arrows. Feel like Thor!! What's not to love?
Then there are games like Beat Saber and Pistol whip. They will take over your life if you let them. Since you like shooting things, you should really try Pistol Whip. Makes you feel like John Wick, really.
Then there are some social games, which is really the strength of VR. The king of social games is Walkabout Mini Golf!! If there is one game you should have in your VR collection, this is it.
But if you really love Half Life Alyx, then fear not, there are ton of mods out there which add new weapons, levels etc.
