I would like to mention that ending really ramps up the difficulty, with giant crit battalions and crit heavies in no short supply. These guys can really hurt you and thanks to the battalions these innately tanky bots (heavies and giants) are now even tougher. Not to mind the convoy of tanks distracting you all the while

General:
-Awkwards payouts, round to nearest 50 or 100
-You might be going too custom for your own good. Getting a propper difficulty or pacing right with unconventional, one of a kind, bots is harder than if you were to use the more conventional valve bots.
-This mission's primary tactic is the spam of small bots, but the robots used and they way in which they are used makes this entire tactic fall flat and has us almost always holding front safely. The giants, which are few, also oft quickly felled posing little challange and dying very quickly
These things made the mission to the testers kind of boring to play
-You're either still misspelling crowd in "croud busters" or croud is a word I'm unaware of
-MamasBaby, ought there not be a space in between the words?
-Your No Fly Zone scouts barely stand out in the crowd, making it hard to assess wether or not they're still on the field, wether or not it's safe to jump now, and makes prioritising them as a target difficult.
Give them a unusual weapon/hat, make them soft minigiants, whatever it might take to have them stand out

W3:
-You have a giant shotgun icon which claims 3 of such bots will appear. Only 1 of the bots under this icon actually uses a shotgun (that I've seen). A wholly different bot under a wholly different icon is straight up missleading

W5:
-$995, really?

W6:
-Seemingly random awkward breaks throughtout, despite having just dealt with a mediocre show of force at best
-The missions bricked, the last 10 heater heavies never did spawn

Congrats, the mission has been passed

I'm not sure what you did to your map but your demo is over half a bloody gig:

This is some funky lighting going on here.

i don't quite understand why you left the remnants of the previous deathpit in. But more to the point and more concerning: why there is a small hole in it you can still fall through. Too small for any robot to shove in, and just large enough to inconvience you when you make 1 wrong move whilst back peddeling.

Because I cannot .nav I'll ask it to be sure: is this route one the bots are taking on their own volition because valve pathfinding, or is it one the mission maker has to specify they will use?

The robots have a tendency to walk more over the raised area with my spray on it, rather than to walk through the lowered area.

Why is there a huge invisible wall over this truck.

The building housing the cap, and the door it opens, both could do with a marking that it is infact A cap and A gate. As simple as it might seem to put 1 and 1 toghether some testers didn't find cap first time around. And when they did, they didn't know what it did. Just pasting the distinctive "A" decals around (notably: the outside of the building, inside, and on/near both sides of the gate) valve has on their caps ought to suffice.

Tanks don't stop to wait for A gate to open, they just phase through it as it opens. We already have working examples of gates where tanks either stop infront of the gate and wait for it to open. Or where you open the gate beforehand as the tank approaches.

Flamethrower noises still persisting even after the flamethrower tank has died. While snd_restart works, is there really nothing that can be done on your end to prevent this?

You can no longer back-cap the gate, yet when it gets captured, the icon does no not display a lock or robot head to indicate it's locked.

Since this is a beta I'll nitpick your detailing:
-Most building look like a boxes, with only the redstone cargo having features that break up its flat walls
-The building that houses the cap reeaally doesn't look structurally sound. With its walls 1 brick thick and a huge, unsupported concrete ceiling it just looks weird. Don't be afraid to throw a pillar in it and maybe beefen up those walls. Might make fighting in it also a bit more interesting as the bottom floor is quite open
-Walls in general are quite thin all around
-Advice regarding brick and mortar: it is really only good to take compressive loads. If brick and mortar has to make an overhang, it'll either need to create an arch or have another loadbearing material to rest on

Bots seem to have trouble walking around this rock

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1760195780
It seems something it's not drawing anything

speaking of the nav, what's causing bots to willy-nilly choose to walk the other way around to catch the bomb if it has been dropped close to hatch/RED spawn? Something like a mere bowmen could pull a sneaky and walk a path other than has been indicated by the bombpath markers and snatch the bomb

There's also still no warning to be heard when a tank enters the field, only once it is halfway

A tank get you squished, and as a result get stuck, in the walls of this tunnel and not die. Be safe and check if this is also the case in other places the tank can squish players, too.

After someone used a bat spell to get the bomb stuck on the outside staircase on the side of the barn, I'd say to consider either:
-Somehow blacklisting spells than can knock/drag bots around unpredictably
-Give the a map a thorough look over for any spots a bomb/bomb-carrying-bot can get stuck no matter how outlandish it might seem. This isn't the most sure-fire approach as someone might just by chance find another spot no one considered to get bots/bombs stuck. Issueing a map update during the campaign is rather tricky.

In the barn there's an invisble ceiling you can bump your head into with jumping upgrades, or with a double jump when, standing on the 2nd floor. This
floor is for some reason made out chainlink fence. I can't imagine walking on them would be awefully comfy, or that such a floor is awefully structurally sound.

Artistic nitpick

This rock wall, and the one in 1st area, both appeared flat to me at first sight. I genuinly thought they were flat untill I started looking closer to notice a very slight bumpiness.
Also consider a larger texture (or upsizing this one) as currently it can quickly start looking repetitve.

W1 and W2 are besides very easy, also very slow now. What with spawning rather few bots, not all that threathening bots at once at a rather slow pace. W2 however does pick up at the end

W5 has turned out to be alot harder than thought, altough I can't really say what any 1 cause for this might be. You might wanna get a looksie at the demo as all I personally experienced was getting wrecked by burstfire demomen
