Quick update on current HUD state.
1. Time and Date. We have universal time/date across all servers, with "starting" date around October 15 2018. Right now day/night cycle is set to be around 4 hours, but we'll be adjusting that during closed beta test to find value that will fit best.
2. You visibility and noise level meters. Faster you move, more visible you're and more noise you're making. Your posture affect your visibility as well.
3. Food and water levels, Health meter, your stamina meter ( only visible when running ) and your blood toxicity meter ( if you got infected ). As you can see I'm really dehydrated right now and I'll be losing health every few seconds if I won't drink something soon.
4. You Primary weapon, melee weapon ( you can have both equipped at same time ) and four of "quick slots" in your backpack. Quick slots are accessible by pressing keys 3,4,5,6 ( default layout ). You can equip any item that can be used on yourself or other players.
5. If you have firearm equipped it'll show how many bullets left in magazine, how many magazines you have, and what current fire mode is ( can be semi auto, 3 burts, full auto - some weapons just have one mode, some have different modes ).
As you can see I'm playing in Hardcore mode so there're now crosshairs on the screen.
