Instant interactive calculations and recipe planners

Generates a steam://connect link and in-game "Connect to IP" candidates. Two conflicting claims exist for the direct-connect port (game port vs game port +2, D2); both candidates are shown with their sources instead of guessing

Triage tree for "not listed / cannot connect / kicked after join": the query-port +2 rule vs panel -QueryPort=27015, the 27020-27050 Steam reserved range, BattlEye (replaced EAC on 2025-05-28), the default MaxPing=200 kick, version mismatch and ExclusiveUsers whitelist

Both wikis (wiki.gg / fandom) plus the Chinese BWIKI, official site and Steam news, BattleMetrics monitoring; community admin tools listed as-is (ScumServerManager, SCUM Admin Helper, the now-EOL SCUM-RCON), each with a source tier - no endorsements

RAM baseline 8GB (official wiki) plus an editable rule of thumb (community claim 1-2GB per 10 players, explicitly unofficial); tickrate 5-30 validation; TimeOfDaySpeed=3.84 gives a 6.25-real-hour game day (pure arithmetic; the community 6h claim is shown alongside, D6); MaxPlayers default 64 vs 128 sold by hosts (D8)

Explicit-formula modelling on official defaults (five respawn options at 250/1000 FP and 1g/2g/3g, the three death/kill coefficients, PermadeathThreshold=-2500). The developer never published an FP formula, so every coefficient is editable and the modelling assumption is stated; the 0.05 FP/min passive rate is a single community source (tier C) used as default

Server admin and config generation (5)

Config files, startup scripts and command wizards for running a server

Derives the official trio from game port P: P (UDP game) / P+1 (UDP raw socket) / P+2 (Steam query); query-port protocol TCP vs UDP shown as conflicting sources (D1); panel -QueryPort=27015 divergence block; hard step >=3 validation for multi-instance; 27020-27050 Steam reserved-range collision warnings; TCP P "RCON (optional)" quoted from the wiki but not recommended (D3)

Windows netsh and Linux ufw flavours; generates the UDP trio from the port matrix; per D1 the query-port rule defaults to UDP with an opt-in TCP checkbox (nothing TCP/RCON is emitted unless explicitly checked); multi-instance batches supported

Anonymous SteamCMD install/update for appid 3792580, the VC++ 2012/2013/2015-2022 and DirectX dependency list, the 64-bit Windows hard requirement, and the unofficial Linux Wine/Proton route (pterodactyl egg and AMP template shown side by side); backups emit copy-only commands (SaveFiles + Config), rotation/deletion is left to the user; graceful Ctrl+C shutdown and the db-wal check

Whitelisted builder for five arguments (-log / -port / -MaxPlayers / -QueryPort panel flavour / -nobattleye behind an explicit danger checkbox) emitting .bat and .sh; C-tier arguments like -serveradminpassword are blacklisted and named but never emitted; MaxPlayers above 64 requires a second confirmation (D8)

Curated-key generator (full file and diff fragment driven by one function, any violation refuses all output, passwords never echoed) + paste pre-check against the official 429-key registry (unknown keys / wrong section / bad type named explicitly) + semantics and tiers of the six admin list files (Admin(1)/SuperAdmin(2)/Elevated(3)) + BigInt SteamID64 validation + a # command quick reference (curated from the 217 reflection-extracted commands, tier-B source stated) + the "no native RCON" fact block
