Zero Caliber VR is an amazing VR title to get if you own a compatible headset such as the Oculus Rift S or HTC Vive. The game has quite a bit of content to go through that should keep you busy.
Pros:
-The game has many missions that took, on average, 15 to 25 minutes to complete for me. Perhaps even more due to searching for secrets.
-The weapon selection is quite nice with many well-known modern weapons as well as some older weapons that are a nice touch.
-The attachment system is definitely very good. There are tons of optics to work with as well as handles, suppressors, and laser/flashlight attachments. This allows for many customization options for your weapons.
-The game likes to reward you for exploring the game as well. There are locked weapon skins that you unlock by going through levels and finding them hidden somewhere out of the way.
As for cons, there are not any major issues that I have encountered. Everything looked and behaved fine. I have had a decent amount of time with the game and have not seen anything game-breaking or inconvenient.
Cons:
-There is a decent selection of levels to go through that I like quite a lot, but once you go through them a few times, it can get a little boring. As the game gets updated, I expect that this will not be much of a problem as they appear to be updating levels here-and-there.
-The game, from what I have seen, lacks any form of mod support. This is somewhat a downside as it is sometimes what keeps games afloat once people have finished all of the missions. With the game being developed on Unreal Engine, I don't see there being any mod support in the near future.
Overall, the game is still great to play. I definitely recommend this game to anyone who owns an Oculus or HTC VR helmet to try this game.
