Based on the Unreal Tournament 2004 mod, up to 6 players fight waves of zombie-like "specimens" in various UK locations. The game combines strategic shopping between waves with intense combat and horrific enemy designs.</p>

<p>Originally a mod released in 2005, the standalone game launched in 2009 and built a massive following. Players select from 7 Perk classes, each with unique weapons and passive abilities that level up through gameplay. The final wave always features the terrifying Patriarch boss.</p>

    <li><strong>Wave-Based Survival:</strong> 4, 7, or 10 waves with boss finale</li>
    <li><strong>The Patriarch:</strong> Iconic final boss with multiple attack phases</li>
    <li><strong>Trader System:</strong> Buy weapons and armor between waves</li>
    <li><strong>Persistent Leveling:</strong> Perks level from 0-6 through gameplay achievements</li>
    <li><strong>Difficulty Levels:</strong> Beginner, Normal, Hard, Suicidal, Hell on Earth</li>
    <li><strong>Mod Support:</strong> Extensive mutator and custom map community</li>

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

<h3>Server Not in Browser</h3>
<pre><code># Check ports are open
netstat -an | grep 7707
netstat -an | grep 7708

# Verify UplinkToGamespy in KillingFloor.ini
[IpDrv.MasterServerUplink]
DoUplink=True
UplinkToGamespy=True

# Wait 5-10 minutes for Steam master server registration
</code></pre>

<h3>Web Admin Won't Load</h3>
<pre><code># Verify bEnabled in KillingFloor.ini
[WebAdmin.WebAdmin]
bEnabled=True
ListenPort=8075

# Check firewall allows TCP 8075
# Try: http://127.0.0.1:8075 locally first
</code></pre>

<h3>Performance Issues</h3>
<ul>
    <li>Reduce <code>MaxPlayers</code> in KillingFloor.ini</li>
    <li>Lower <code>NetServerMaxTickRate=20</code></li>
    <li>Disable complex mutators</li>
    <li>Use <code>-benchmark</code> flag to test server performance</li>
</ul>

<h3>Custom Maps Not Downloading</h3>
<pre><code># Enable downloads in KillingFloor.ini
[IpDrv.TcpNetDriver]
AllowDownloads=True
ConnectionTimeout=60.0

# Set up redirect (FastDL)
DownloadManagers=IpDrv.HTTPDownload

[IpDrv.HTTPDownload]
RedirectToURL=http://yourdomain.com/kf/
</code></pre>

<h3>Perk Progress Not Saving</h3>
<ul>
    <li>Ensure server connects to Steam (<code>VACSecured=true</code>)</li>
    <li>Players must be logged into Steam</li>
    <li>Check <code>System/KFStatsAndAchievements.ini</code> for errors</li>
    <li>Perk data stored server-side via Steam ID</li>
</ul>

    <h3 style="color: #ffffff; margin-top: 0;"><i class="fas fa-lightbulb" style="color: #fbbf24; margin-right: 8px;"></i>Pro Tips</h3>
    <ul style="color: #fef3c7; line-height: 1.8;">
        <li><strong>Web Admin Essential:</strong> Much easier than console commands</li>
        <li><strong>Balanced Perks:</strong> Encourage teams to use diverse perk combinations</li>
        <li><strong>Medic Critical:</strong> At least one Medic greatly improves survival rates</li>
        <li><strong>Classic Maps:</strong> BioticsLab, Farm, and WestLondon are community favorites</li>
        <li><strong>Suicidal+ Only:</strong> Most active players prefer Suicidal and Hell on Earth</li>
        <li><strong>Mutators:</strong> Use sparingly - too many can cause instability</li>
        <li><strong>VAC Secured:</strong> Always enable for legitimate perk progression</li>
        <li><strong>Custom Content:</strong> Active custom map community, but test before adding to rotation</li>
    </ul>
