Onward, great bomb-cart!
— The Heavy
Payload is a game mode in which the BLU team must escort a cart, usually full of explosives, through a series of checkpoints and into the RED team's base within a certain amount of time.
Payload Race is another game mode based on Payload, in which both the RED and BLU teams have an explosive Payload. To win, each team must push their cart through enemy territory to reach the finishing point while preventing the enemy team from doing the same.
The cart is pushed by standing next to it – the more people there are, the faster it moves, up to a limit of 3 players. Any additional players beyond 3 do not increase the speed further.
- Scouts and players carrying the Pain Train count for two people.
- If a member of the opposing team stands near the cart, it is blocked, and the cart does not move until the opposing player leaves or is killed.
- Disguised Spies count normally as whichever team they are disguised as: If disguised as an enemy, they block the cart, if disgused as a friendly, they push the cart.
- Disguised Spies do not get bonuses when disguised as Scout, nor if the character they are disguised as is using the Pain Train.Confirmation needed
- Players under the effect of an ÜberCharge from either the Medi Gun or Quick-Fix do not count for nor block the Payload (the Kritzkrieg and Vaccinator ÜberCharges have no impact on pushing the Payload).
If the cart is left unattended, it stops moving forwards and, after 30 seconds, it begins to roll backwards until the previous checkpoint. The cart-pushing team must stand next to it again to once again move it forwards.
On some maps, there are special incline slopes or rollback zones, where an unattended cart rolls backwards. In these zones, the cart-pushing team must continuously stand next to the cart to get it up such hills. These sections of track are marked with chevrons on the progress bar, to help show how far the cart must be pushed to overcome them. Once passed, the cart cannot roll back past down these slopes, so they act as a sort of checkpoint.
Currently, all Standard Payload maps use the same cart speed. Speeds are measured in Hammer units per second.
If any buildings are placed on the tracks, the building is destroyed as the cart passes through it. The cart works as a Level 1 Dispenser for the team it belongs to, restoring health and ammunition to those pushing it. Unlike Level 1 Dispensers, the cart does not have a limit to the amount of metal it can give to Engineers. It also provides ammo and health to disguised enemy Spies.
As of the Engineer Update, the cart has a glowing, team-colored outline effect that enables its position to be identified through walls and from further away, allowing players to keep an eye on its whereabouts at all times.
In Payload, the BLU team must push a cart through a series of checkpoints and into the RED team's base within a certain amount of time. Reaching a checkpoint adds time to the timer.
If a BLU player does not push the cart after 30 seconds have passed, the cart starts slowly moving backwards 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 occurs, which gives the attacking team five seconds to move the bomb until they lose. The timer resets each time the cart is pushed.
In Payload Race mode, both teams are issued a cart. The teams must simultaneously push their cart through enemy territory while preventing the enemy team from doing the same. Unlike Payload maps, the cart does not move backwards after any length of time (unless it is on an inclined slope) 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 maps. During Overtime, both carts automatically move forward slowly to prevent Stalemates. Pushing one cart stops the other from moving forward by itself. If the carts' tracks cross paths, and both carts arrive at the intersection at the same time, one cart waits for the other to pass by even if players are on both carts.
Li'l Chew Chew
On the Payload map Frontier, a substantially larger mechanized train engine known as Li'l Chew-Chew is used in place of the standard BLU cart. It has movable jaws with razor-sharp teeth and two headlights as eyes, and a rideable platform on the back.
Providing cover from frontal attacks, Li'l Chew Chew is capable of significantly damaging any player (of either team!) in its mouth when it is moving forwards. The damage done increases as more players ride its rear platform; three or more attackers cause the jaws to deal an instant-kill by "swallowing" the victim whole, leaving no corpse. The platform also has a built-in BLU Dispenser; however, those riding on it have trouble seeing directly in front of the cart, as the main body of the train is in the way. It has a noticeably increased pushing range when compared to normal carts. It cannot be blocked by opposing players from RED team standing in front of it, only when opposing players stand near or on top of the train's platform. Rudy, a modified variant of Li'l Chew Chew, appears in Wutville.
Payload maps may be split into multiple rounds, such as Gold Rush, Hoodoo, and Thunder Mountain. These are split into three stages that the BLU team must advance through and win. Stages one and two have two checkpoints and stage three has three checkpoints (two for Hoodoo), counting the final point as such.
Badwater Basin and Upward have a single round with four checkpoints, including the final point. Advancing the cart to the next checkpoint gives the BLU team extra time. Advancing the cart to the final point moves the map onto the next stage. When the cart reaches the final point on the final stage, the Payload cart explodes, killing anyone standing too close to it and destroying the RED team's base as well.
Payload Race maps can be single or multi-stage. Pipeline and Nightfall are split into three stages, whereas Hightower consists of only one stage. Winning in each of the first two stages gives an advantage to the winning team in the next stage (the cart starts slightly forward from the starting point).

- The cart may sometimes randomly spin vertically.
- The capture progress HUD sometimes does not report how many players are pushing the cart. It may also display the cart as being blocked when it is not.
- Dying due to the cart explosion causes the Deathcam to focus on a specific point of the map while displaying the name of an opponent, even if no enemy was involved in the player's death.
- It is possible to derail the cart as it is falling by launching it with an explosion. This works because it becomes a physics prop when it reaches the end of the track.
- A very rare glitch occurs when the doors to BLU do not open, and the map stays in Setup Time. The cart slowly pushes itself and cannot be blocked.
- Occasionally, a Payload cart may be already moved from its default position at the start of a round, even if it has not been pushed and the game is currently in Setup time.
- If a player repeatedly picks up weapons on top of the final checkpoint on certain maps, the dropped weapon may slip through the hatch and detonate the final checkpoint early.
- On certain spots the player can be pushed inside of map geometry, such as the tunnel exit before Upward's 2nd point while standing on top of the cart.
- It is possible to get stuck inside buildings this way.
- The default Payload takes the shape of a "Fat Man" implosion-style plutonium atomic bomb. This type of bomb was dropped over Nagasaki during World War II.
- Hoodoo uses a different cart model. 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.
- On some of the carts, there is a Heavy quote written into the paintwork:
- The default cart bears the words 'Cry some more' scratched into the paintwork.
- The Hoodoo cart has the words 'So much blood!' painted in white on the front-most barrel and the word 'Bonk' written in dust underneath one of the straps.
- Lil' Chew-Chew bears the words 'All of you are dead!' scratched into the paintwork in front of the smoke stack.
- The light on the Payload cart is the same as the one duct-taped on the Combat Mini-Sentry Gun.
