Just a couple tips that have kept me alive and reluctant to throw my computer out of the window for a long time, until some hacker shows up...: 1. Barrel rolls (pressing Q or E while prone) make absolutely no noise, and so does vaulting. This has helped me tremendously in being stealthy whilst trying to sneak up behind some highly-geared/skilled sniper that's perched up on a tower or hidden in the tree line. I once rolled up behind some bandit that was killing newbies at Elektro with his AS50 and I only had a hatchet; we ended up killing each other but you should've heard the sniper's scream over the microphone after the first slash :P. Plus, it makes you feel like a ninja after getting a murder :) 2. No matter how visible you are, as long as you're not in the zombie's complete line of sight he will not get aggro. However, zeds can still hear you, so you need to monitor the amount of sound you make at all times. 3. ALWAYS assume that the person you just murdered/saw has companions that are within the proximity. I have made the mistake of thinking that my victim was playing alone numerous times, resulting in a shocking and devastating death :(. Patience is virtue; do not be so eager to collect your spoils of war until you're 100% sure that your victim is dead and there's no one else in the area that may be affiliated with him. 4. If you're playing with a friend or numerous friends (highly recommended) then it's imperative that at least one of you should stand watch whilst your teammates loot the area. This might prolong the looting time as you and your friends might decide to switch roles in case the overwatch also wants a share of the loot, but it's better to be safe than sorry. 5. Always drop a pointless item first before dropping a rare item on top of it; there are places in Chernarus where dropped items are said to never return.... 6. If you continue to put massive items in an already-full backpack/inventory, shit's gonna disappear.
