Carts are the objective and focus of the Payload and Payload race game modes.

Carts are attached to a line of railroad tracks; the objective is to push the cart along said tracks, while the enemy team attempts to stop it. The cart is pushed by standing next to it - the more people, the faster it moves (up to a maximum of 3). If any opposing team member gets near the cart, it is blocked and the cart will not move until the opposition is removed. The cart acts as a level 1 Dispenser for the team that owns it, restoring health, ammo, and metal.

If a cart is left unattended on specific slopes, it will naturally roll down it. The cart-pushing team must push it continuously to get it up such hills, whereas reaching a downwards slope becomes a sort of checkpoint that the cart cannot reverse past.

Payload Mode

In Payload mode, BLU must push a cart through a series of checkpoints and into RED's base within a certain amount of time. Reaching a checkpoint adds time to the timer. If no BLU player pushes the cart after 30 seconds have passed, the cart will start moving backwards slowly until it reaches a checkpoint/BLU spawn or a BLU player stands next to it again. If the cart is not moving backwards when time runs out, Overtime will occur, which gives the attacking team five seconds to move the bomb, or they lose. The timer resets each time the cart is touched.

Payload Race Mode

In Payload Race mode, both teams are issued with a cart. The teams must simultaneously push their cart through enemy territory while preventing the enemy team from doing the same. Unlike Payload mode, the cart will not move backwards after any length of time and there is no time limit; the map only ends when one team successfully pushes their cart to the finish point. Payload Race maps tend to use rolling slopes much more than standard Payload ones.

Cart Speeds

Concept Art

Cart bomb model found in game files that resembles above concept art.

The speed of the cart depends on the amount of people (the multiplier) that are pushing. Currently, all stock Payload maps use the same speeds. Speeds are measured in hammer units per second.

Multiplier	Speed	Rate
(Backwards)	-9	-10%
x1	50	55%
x2	70	77%
x3	90	100%

Note: The capture limit is 3 players. Any more will make no difference

Trivia

• The Payload takes the shape of a "Fat Man" implosion-style plutonium Atomic Bomb. This bomb was dropped over Nagasaki, Japan on August 9th, 1945 at 11:02 JST.
• Hoodoo uses a different cart model, having once been a community map. The map description reveals the cart to be carrying a 'dirty bomb'; a nuclear explosive consisting of little more than radioactive material strapped to conventional explosives, such as TNT.
• Though the Hoodoo cart uses an improvised timed detonator, it does not explode at the end of the round unless BLU is successful.
• The default cart bears the words "Cry some more" scratched into the paintwork, likely by the Heavy.
• Similarly, the Hoodoo cart has the words "So much blood!" painted in white on the frontmost barrel, and the word "Bonk" written in dust underneath one of the straps.
• There used to be a bug in game where an Engineer could upgrade the Dispenser on the cart, allowing it to give increased healing, ammo and metal. This has since been fixed.
• As of the Engineer update, carts have a glow effect that can be seen through walls.
