Pluginy AMX Mod X

ELO rating for mix/match play in MySQL: winners gain and losers lose points by the rating gap, with /elo, /topelo and ELO-balanced teams.

Evens the teams at round end by moving the lowest-scoring players, with an optional skill mode.

Per-team gravity multipliers applied on every spawn with set_user_gravity; reset to normal when disabled.

Captain draft: two captains pick players alternately from a menu into balanced teams, with a turn/roster HUD.

Automatic 5v5 mix: /mix queues players, balances two teams by rank, plays a knife round and starts the match.

A menu of the cvars admins change most (friendly fire, gravity, freeze/round/buy time, team balance, start money, C4 timer) that cycles preset values inline.

An nVault-backed ammo-pack currency: earn packs for kills, headshots and round wins, persisted by SteamID, with natives so a shop plugin can spend them. /packs shows the balance.
