Botkiller Weapons
Kills: 0
(Robots Destroyed: 0)
Silver attachment applied

Changes
All Botkiller weapon reward drops have a 'Strange Part: Robots Destroyed' attached
Botkiller weapons now have alternative styles to change the botkiller attachment type

Reason
This may encourage MvM players to use these weapons more as they have in-built robot kill tracking.

Botkiller Dismantler
Use on Botkiller weapon to consume the weapon and redeem the Botkiller attachment, which can be applied to another Botkiller weapon of a different type to unlock an alternative style.

This is a limited use item. Uses: 1

Changes
Botkiller dismantlers are the only way of applying new alternative styles to Botkiller weapons
Botkiller weapons lists every attachment type assigned within the stats

Reason
This is mainly to reduce inventory bloat and to provide somewhat of a sink for botkiller rewards. Regular MvM players can work towards earning 'Trophy' botkillers that have every botkiller type attached.

Squad Surplus Voucher
Present this voucher in Mann vs. Machine when starting Mann Up Mode. Each team member that activates one will add an additional reward for all members upon completing the mission.

Changes
Guarantees one of the following rewards upon completing any mission:
40% chance to receive 1 random weapon drop
30% chance to receive 2 random robot parts
20% chance to receive 1 random rare robot part
10% chance to receive 1 random robot cosmetic item

Reason
Many find the cost of $1.99 to be a bit steep for 6 weapons and a rare chance at a robot cosmetic. The pool of rewards has been expanded on and chances of getting alternative rewards are more probable.

Operation Oil Spill
Difficulty: Intermediate
Doe's Doom (Decoy)
Day of Wreckening (Decoy)
Cave-in (Coal Town)
Quarry (Coal Town)
Mean Machines (Mannworks)
Mannhunt (Mannworks)

Rewards
Upon completing a mission:
1 weapon item drop (gauranteed)
5-7 robot parts (gauranteed)
Upon completing a tour:
2 rare robot parts (gauranteed)
1 Rust Botkiller MK.I weapon (gauranteed)
or 1 Blood Botkiller MK.I weapon (rare)
1 Australium weapon (extremely rare)

Reason
As the easiest mission to complete, while also having the most missions (6) to complete its tour. It seems appropriate to offer a grinding purpose to play through it. Each mission complete offers a significant amount of robot parts to nearly ensure youll get what you need to complete your fabricators. The small chance for an Australium weapon was put in so players do not feel like they are sacrificing the chance.

Operation Steel Trap
Difficulty: Advanced
Disk Deletion (Decoy)
Data Demolition (Decoy)
Ctrl+Alt+Destruction (Coal Town)
CPU Slaughter (Coal Town)
Machine Massacre (Mannworks)
Mech Mutilation (Mannworks)

Rewards
Upon completing a mission:
1 weapon item drop (gauranteed)
1-2 robot parts (gauranteed)
1 Strange Part (rare)
Upon completing a tour:
1 Silver Botkiller MK.II weapon (gauranteed)
or 1 Gold Botkiller MK.II weapon (rare)
1 Strangifier Fabricator (rare)
1 Australium weapon (extremely rare)

Reason
Offering additional alternative rewards allows for variation in tour selection. This tour adds the reward of Strangifier Fabricators, which will require robot parts to complete, as well as Strange Parts. The pool of items that can be Strangified has been expanded, giving an incentive to seek out ones you cannot normally obtain elsewhere. Requiring 6 missions to complete and no gaurantees of getting either exclusive reward, this will only be for those willing to put some money into it.

Operation Mecha Engine
Difficulty: Advanced
Disintegration (Decoy)
Broken Parts (Bigrock)
Bone Shaker (Bigrock)

Rewards
Upon completing a mission:
1 weapon item drop (gauranteed)
1-2 robot parts (gauranteed)
Upon completing a tour:
1 Rust Botkiller MK.I weapon (gauranteed)
or 1 Blood Botkiller MK.I weapon (rare)
1 Botkiller Dismantler (garunteed)
1 Australium weapon (extremely rare)

Reason
Offering additional alternative rewards allows for variation in tour selection. This tour adds a new reward that will help build up botkiller weapons, known as Botkiller Dismantlers. With one gauranteed every 3 missions, this should be easy enough to grind out for some botkillers.

Operation Two Cities
Difficulty: Advanced
Empire Escalation (Mannhattan)
Metro Malice (Mannhattan)
Hamlet Hostility (Rottenburg)
Bavarian Botbash (Rottenburg)

Rewards
Upon completing a mission:
1 weapon item drop (gauranteed)
2-4 robot parts (gauranteed)
1 rare robot parts (rare)
1 Specialized Killstreak Fabricator (rare)
Upon completing a tour:
1 Killstreak Kit (gauranteed)
1 Specialized Killstreak Fabricator (gauranteed)
1 Professional Killstreak Fabricator (rare)
1 Australium weapon (extremely rare)

Reason
Previously the only tour worth doing for its amount of gauranteed rewards, Operation Two Cities has had its robot part reward count dropped. Instead, Operation Oil Spill (the easiest and longest mission) has been given the title of robot part grinding. Operation Two Cities will keep its Killstreak rewards as is for those who wish to grind for them.

Operation Gear Grinder
Difficulty: Expert
Desperation (Decoy)
Cataclysm (Coal Town)
Mannslaughter (Mann Works)

Rewards
Upon completing a mission:
1 weapon item drop (gauranteed)
1-2 robot parts (gauranteed)
Upon completing a tour:
1 Carbonado Botkiller MK.I weapon (gauranteed)
or 1 Diamond Botkiller MK.I weapon (rare)
1 Collector's Kit Fabricator (very rare)
1 Australium weapon (extremely rare)

Reason
Offering additional alternative rewards allows for variation in tour selection. This tour has a very rare chance of rewarding a Collector's Kit Fabricator, which will require robot parts to complete. What used to be obtainable can now be grinded out through a 3 mission tour, though with no gaurantees.

Gamble with caution.

Refund Credit Pool
Each player has an upgrade refund credit pool, which allows them to refund any singular upgrade point if the cost is not larger than the refund pool
Refund pools carry over into every wave

Changes
The refund pool amount will appear in the bottomn right corner of the upgrade station HUD
After wave completion, all bonus credits earned and 25% of credits collected are added to the refund pool
Refunding an upgrade reduces the pool by the upgrade cost.

Reason
This allows some upgrade flexibility while keeping the challenge of the waves/missions. For instance, some upgrades such as fire resistance, can be refunded if the future waves do not require it.

Power Up Canteen
Currently holds 0 charges
Holds a maximum of 3 charges
Each charge lasts 5 seconds
Applies a bonus effect for a limited amount of time when used. Must first be filled at an Upgrade Station and can only be filled with one bonus type at a time.

Changes
Canteens cannot be activated until wave start
Current held charges tooltip changed to be yellow and moved to top of the stats list
Sentry Guns only benefit from canteens when the Canteen Specialist upgrade is purchased

Reason
This will prevent players from accidentally activating their canteens before the wave begins. One side effect is that Demoman must make crit sticky traps as the wave starts. The text change was to make the current charges more visible for spectating players.
