Shoot Many Robots

This should come easily through time playing if you are trying to do this by yourself. However, stage 6 "downtown roadblock 2" survival isn't too hard and you should be able to kill 760-800 robots each time you do it. It definitely will save you some time. Good luck and enjoy!

Hi! I've been told that my solutions are too long, so short version first, explanation version after that if you like to read.
Quick description: Hard difficulty, Chapter 7, Outskirts Ambush, killing everything until the bonus wave netted me 298 kills in 2:15, killing everything until the balloon netted me 570-600 kills in 4:30. Die at either of those and repeat. Completing the chapter is not worth it!


Long description:
Got my level 50, and still didn't have 10k robot kills, so started trying to find the best method.
There is a hard level, that works wonders: Hard difficulty, Chapter 7, Outskirts Ambush.

For this level, I was able to get 570-600 kills in less than 4.5 minutes. You simply need to annihilate everything from the start as fast as possible, which is extremely easy with level 50 weapons, and easy enough with other weapons too(I recommend fluffy as a secondary otherwise, it works great for clearing the entire map, especially of air enemies!)
You can also go with the 2 minutes and 15 sec solution, die as soon as the bonus wave starts, but because of loading times probably not quite as fast. You will get 298 enemies though every-time, at least I did, dying at the start of the bonus round.
I found that it took just over 2 minutes to get to the first bonus wave.. and I would die on purpose as soon as the first balloon showed up in the first bonus round. That nets just under 600 kills depending how many you kill after the balloon shows up. :-) After that point it's not really worth continuing, as I found I had about a total of 700-800 for the rest of the mission.

I was amazed how many kills I had NOT gotten on my way to level 50. I was sure I'd get the 10k kills first, but since I played with so many other people, and got so many levels from playing with higher level players, I still needed to get 3-4k kills after reaching 50.

Hope this helps, suggestions and comments are welcome!

Btw, I didn't like the other level recommended in the other solution because of the sometimes slow spawn rate, having to wait for stuff, and having to move around so much. Outskirts Ambush is nice because you hardly ever have to jump, and can just run/walk back and forth.

My loadout for this was:
"The Greedy Svidrigailov": Damage/sec 9-1199; Acc. Okay; Rate of Fire: Very Fast; Range: Short; Crit Dmg: 4x; Nut Suck Radius +100%.
"Ultra-Light Warsaw"(I used this for aerial enemies and the one shielded sawblade): Dmg/sec 548-1917; Acc: Very Good; Rate of Fire: Very Fast; Range: Medium; Crit %: Very High; Speed -7%; Ammo 100.
"King Normal's Crown": All dmg: +139%; Hangtime Rating 7; Slam Power 7; Slide Rating 7.
"Gary The Undead Gnome": All dmg: +204%; Explosive dmg: +383%.
"Mesozoic Soldier's Belt": All dmg: +136%; Bullet dmg: +272%; Ammo +20%.

This is more of a tip than a guide but you can use any of the above 2 methods and can use the Shoot Many Robots save editor and load your save in the editor and it shows you your current kills, i dont condone editing the kills but its handy to show how many you currently have:
