Players are able to customize their in game experience and navigate the gamemode through the use of NPCs. These NPCs are the Queue Machine, Server Leaderboard, Battle Upgrader, Gun Dealer, Model Vendor, and Help Desk.

The Queue Machine is where players get in a line for a one versus one tower defense match. The standard map ( td_battlehall ) supports up to eight players playing at once. Once your match is ready a pop up will appear on your screen to confirm you are ready.

The Server Leaderboard lists the top 25 players on the current server. This leader board updates after each match played and is organized by highest Rating.

Battle Upgrader allows players to use TDPoints and TDCoins to purchase and select Abilities to be used in a match.

Gun Dealer offers Upgrades to help improve the performance of the player's Ultimate Tower.

Model Vendor allows players to use TDPoints and TDCoins to purchase and select player models for the player.

Help Desk offers in game help on common topics for new players. Here players may also exchange TDCoins for TDPoints.
