An Upgrade Station is a place for players to buy weapon upgrades, abilities, and Power Up Canteen buffs in Mann vs. Machine. Players may access one of the two kiosks in the base at any time to purchase upgrades with collected credits. The cost of each upgrade does not increase with a repeated purchase. Between waves, players may modulate the number of levels in an upgrade by pressing the + and - buttons to redistribute their credits if they have made a mistake before accepting the upgrade. Once accepting the upgrade it cannot be revoked unless all upgrades are refunded.
During the setup of the first wave of the mission, upgrades can be sold back if the player wants to change weapons, classes, or buy a different upgrade. During the setup for each wave, players may refund their upgrades in the upgrade station menu as many times as necessary. A Wrench icon () will appear next to a class in the Class Selection Menu if that class already has upgrades applied to it. Weapon upgrades apply to only a single weapon but take effect for all classes that can equip the weapon. Un-equipping a weapon will deactivate all upgrades associated with that weapon, but they will be regained if the player re-equips it. Disconnecting from a server and rejoining will allow the player to retain the player current amount of credits and upgrades if the player chooses the same class.
Failing to complete a wave will refund the credits spent before that wave to give the player a chance to use a different strategy. Otherwise, credits will not be refunded after accepting the upgrades.
Since there are no Resupply Cabinets in the base, purchasing an upgrade from an Upgrade Station will restore health and ammo without needing to switch classes. Players cannot heal using the Upgrade Station during waves.
Upgrade Stations are accessed by walking up to them. By default, the primary weapon slot is selected. The UI automatically shades upgrades in a slot if the player cannot afford them. Players may hit the "Cancel" button at any time or simply walk away from the kiosk before accepting an upgrade to regain the credits used during the session.

- There are many additional sound files for Projectile Shield upgrade, they're referred into the game files as "
prefix_burn_suffix", those probably would be used when multiple projectiles have been protected by the Projectile Shield. There is also another unused sound that would be used if the user retracted the shield after switching weapons.
- Inside the game files, there are 3 upgrades to be found that are not currently in the game; They include a radius of Sentry Gun upgrade, regeneration of a percent of a mercenary's max ammo every 5 seconds upgrade, and gaining more credits through an additively stacking percent multiplier upgrade.
- There is an unused song in the game's files that would possibly be played while the player used an Upgrade Station.
- Changing a weapon via loadout screen before walking up to the upgrade station, then buying a single upgrade, will prevent buying or selling any upgrades.
- The descriptions for the reload speed and firing rate upgrades are slightly misleading. Rather than making these actions a set percentage faster, they actually reduce the function time by the stated percentage. E.g. A weapon with a cumulative 60% faster reload time will reload in 40% of the normal time (i.e. 100% - 60%), not 62.5% (100% / 1.6).
- Occasionally, when on the Canteen charges page, clicking once on any upgrade's + sign will give the player two charges for the Canteen, at the same cost of purchasing one charge twice, though only one circle fills. The player will end up with those two charges upon clicking "accept", and the interface returns to the correct number of circles filled the next time the player goes to the kiosk.
- The upgrade screen will suddenly disappear for the Engineers if their teleporter is taken during this time. Any upgrade the Engineer was purchasing will be lost, but the money will be returned.
- Any chat notifications will immediately exit the upgrade station menu.
- The Heavy primaries and Sentry Gun's firing speed upgrades are glitched:
- Miniguns' second firing speed upgrade has no effect; thus, buying all four upgrades effectively increases firing rate by 30% instead of 40%.
- Sentry Guns don't benefit at all from the last upgrade and unwrangled Sentry Guns are not improved by the second upgrade.
- There are several items visible inside the Upgrade Station, the most notable being one of the many scrapped weapons used for the scrapped grenade slot, which are the Bear Trap and the Frag Grenade.
- The texture for the Upgrade Station contains a hidden note in the top left corner, which cannot be seen in-game, which says:
"WEAPONS OF THE DAY: GRENADES FREE AMMO REFILL WITH PURCHASE
HAVE A NICE DAY. DON'T DIE, OR, WELL, DO DIE... WHATEVER. JUST DON'T GET BLOOD ON MY FLOOR."
