AMXX Pawn plugin

i need to do Deathrun duel plugin. In the end all maps will be button (button will spawn admin manually with any command). When CT press this button, it will open duel menu for him with: - deagle (one bullet in the tray with reloading) - awp (one bullet in the tray with reloading) - knife - he grenades - famas, etc. When CT choose duel gun, then will start the timer (3 seconds). After that, CT and T will do duel. If will some other CT meanwhile press end button, he will queued. If win T, duel menu will open for next CT in queue. During duel nobody can hurt this 2 playes (CT and T). Some plugins for that already exist, but there is no any queue and no end button. Etc: [url][login to view URL][/url]
