My server runs on SPT 3.11.4, meaning you'll need the downgrader (~7GB).
Step 1: Install EFT Live from Battlestate/Steam/Epic Games (73GB).
Step 2: Copy everything from Live and paste it into a new folder named SPT Temp or something.
(KEEP YOUR LIVE INSTALL. YOU CAN'T PLAY SPT WITHOUT IT.)
Step 3: Extract and run the downgrader in the SPT Temp folder.
Step 4: Run EFT Live once to generate necessary files, then run the SPT Installer.
Step 5: Install FIKA, then install 20GB of mods.
Step 6: Wait for Kenzo to give you server-specific mod configurations.
Step 1: Install Radmin VPN.
Step 2: Find Network>Join Network
