TotalDead

New items: Adrenaline, Splint, Backpack
Adrenaline, when used, imposes a speed effect and a strength effect on you for 2 minutes
A splint is needed when a bone is broken, which can be obtained if you step into a bear trap
I think the functions of the backpack do not need to be explained

New weapons: Pole, spear, molotov coctail
The pole is the most simple weapon that deals 3 damage. Can be crafted from 2 sticks
The spear is an upgraded pole with an iron tip and deals 5 damage
Molotov coctail sets entities on fire when hit but does not set blocks on fire

New blocks: Mine
Explodes on contact with an entity, dealing quite a lot of damage

New visuals: Low HP overlay, infection third stage overlay
If your health is below 5, you will get a bloody overlay and heartbeat sounds will start playing
If your health is below 2, the screen will turn more reddish and your heart rate will increase
If you have infection third stage, an overlay in the form of green veins will appear on the screen

New mobs: The Dried up, Burned zombie
The Dried up is very weak type of zombies that moves so slow and deals little damage, but it still can infect you
Burned zombie spawns only in nether wastes biome. It leaves a trail of fire behind it and sets you on fire when it attacks. He is as slow as The Dried up and still can infect you.
