Ammo exchange kiosks or just exchange kiosks, are booths set up in most civilized metro stations. Acting as banks and supply stores, the kiosks provide an exchange service for the player if they need different ammo types. Exchanges are always between military grade rounds and the other ammo in question with selling rates always half of buying rates. Ammunition types will appear as they become introduced and available in other action-stage tunnels. Holding down the accept command will make the exchange happen faster for quick transactions.
