<h2 id="overview">Overview</h2>
<p><strong>Killing Floor 2</strong> is a brutal wave-based co-op FPS where teams of up to 6 players fight through hordes of genetically engineered monsters (Zeds) developed by the Horzine Biotech Corporation. Each player selects a unique Perk class with specialized weapons and abilities.</p>

<p>The game features a sophisticated economy system where players earn "Dosh" during waves to buy weapons, ammo, and armor. Between waves, players strategically shop at Trader Pods scattered across maps. The action culminates in an epic boss battle after the final wave.</p>

<h3>Key Features</h3>
<ul>
    <li><strong>10 Perk Classes:</strong> Berserker, Commando, Medic, Demolitionist, Firebug, Gunslinger, Sharpshooter, Support, SWAT, Survivalist</li>
    <li><strong>Wave-Based Survival:</strong> 4, 7, or 10 waves with scaling difficulty</li>
    <li><strong>Boss Fights:</strong> Multiple unique bosses (Hans Volter, Patriarch, King Fleshpound, etc.)</li>
    <li><strong>MEAT System:</strong> Realistic gore and dismemberment system</li>
    <li><strong>Weapon Trading:</strong> Buy, upgrade, and share weapons with teammates</li>
    <li><strong>Difficulty Levels:</strong> Normal, Hard, Suicidal, Hell on Earth</li>
    <li><strong>Weekly Outbreaks:</strong> Special modifiers and challenges rotate weekly</li>
</ul>

<h2 id="troubleshooting">🔧 Troubleshooting</h2>

<h3>Server Not in Browser</h3>
<pre><code># Check ports are open
netstat -an | grep 7777
netstat -an | grep 27015

# Verify GamePassword is empty in PCServer-KFEngine.ini
[Engine.AccessControl]
GamePassword=

# Restart server and wait 5-10 minutes for Steam registration
</code></pre>

<h3>Web Admin Won't Load</h3>
<pre><code># Verify KFWeb.ini settings
[IpDrv.WebServer]
bEnabled=True
ListenPort=8080

# Check firewall allows TCP 8080
# Access via: http://server-ip:8080
</code></pre>

<h3>Performance Issues</h3>
<ul>
    <li>Reduce <code>MaxPlayers</code> to 4 or lower</li>
    <li>Set <code>NetServerMaxTickRate=20</code> in PCServer-KFEngine.ini</li>
    <li>Lower resolution: <code>ResX=640</code>, <code>ResY=480</code></li>
    <li>Disable blood decals: <code>bAllowBloodDecals=False</code></li>
</ul>

<h3>Workshop Content Not Downloading</h3>
<pre><code># Verify Workshop item IDs in PCServer-KFEngine.ini
[OnlineSubsystemSteamworks.KFWorkshopSteamworks]
ServerSubscribedWorkshopItems=123456789

# Check KFGame/Cache/ for downloaded content
# Restart server after adding new Workshop items
</code></pre>

<h3>Players Can't Join</h3>
<ul>
    <li>Check firewall allows UDP 7777 and 27015</li>
    <li>Verify <code>MaxPlayers</code> setting</li>
    <li>Ensure server isn't password-protected unless intended</li>
    <li>Check server logs in <code>KFGame/Logs/</code></li>
</ul>

        <li><strong>Workshop Maps:</strong> Keep official maps for 95% uptime, custom for variety</li>
