$$$ FEW OTHER TIPS I FORGET ABOUT $$$
1.
If you get Grande Lauchers or RPGs discard them altrough they are powerfull, you dont need it much. By the time you get Grande Laucher you probably will have good weapons .
2.
Dont bring with yourself not used items such random trash or clothes .
3.
If your hurt dont use medical items , try to use items such as food. It helps you not that much but you can lose weight.
4.
Use SPACE button to kick zombies. It helps if your surrounded by many of them.
5. The best melee you can get if you open some achivements is battle axe , it weight is 14KG but attack is
6.

7.
