Here are the things I wish to see in future updates.
(Some of these might have been in the game and I just didn't noticed )
1. General Mechanics and Realism
-Proper Sleep and Resting Animations
-Loot Sheets from Beds
-Craftable Pillows or Sheets
-Craftable Bags/Sacks/Rucksacks
-Lie Down on bed/Sit on chairs to rest
-Sit on any surface slightly higher than the floor or on any seat-like object like boxes or furniture
-The character must find the closest object to lean or sit on when resting and not just stand there for hours like a maniac
-Rain should soften and destroy cardboard boxes
-Proper Animation when using shower and bath tubs to clean self
-Zeds randomly attacking other zeds
-Make items 'visible' on pickup truck container
-Pockets on clothing as small containers - this should be craftable as well
-Exploding Tanks/Fuel Containers
-Improve the appearance of dropped loot
-Peeking through door peep holes or small holes/cracks on walls
-Trees should fall as fallen trees, this should block the pathway, fallen trees can be chopped down to logs using the axe
-Trees could fall naturally over time or if there is strong wind or if they are partially chopped by the player
-Pouring Cleaning Liquid on glossy floor should make it slippery for both player and zeds
-Dismemberment
2. Abilities
-Leaning on walls and peeking on corners
-Throwing stuff to make noise
-Throwing weapons on enemies
-Setting up traps
-Going Prone/Crawling
-Dual-wield: Use primary and secondary weapons simultaneously - like pistol on the right hand and machete on the other
-Create Bonfire using pile of trash or dry leaves in the woods. Make trash/leaves pile using rake.
-Expanding vision using mirrors: Facing the mirror should make the behind visible or strategically placing the mirror on walls to make you see around corners - you get the idea
3. Crafting/Building/Furniture
-Dragging furniture across the floor for quick blockage of passageways
-Use tabletops and furniture surface as container like the chairs on vehicles
-More Non-Glass Window Variation
-Fixed and Movable Ladders
-Building Underground Bunkers
-Living Potted Plants
-Craft improvised light source from car batteries and lightbulbs
-Adding Pillows and Sheets on Couches of Beds to slightly increase bed quality
-Somewhat realistic plumbing and wiring system
-Wind make curtains/sheets on open windows/doors move: this should also affect visibility
