I've bee playing it since it came out, consider myself a good player, but for the life of me I can't get to 150 on any map. I get to 130 and time runs out. I grab the timers; melee kill most things; and counter bloodshots but can't even seem to get close enough.
Easiest to me seems to be Rooftop with Carla or Sherry's alt.Only played a few times though. I have several S ranks between Urban, Requiem, and Rooftop as well.
Yes, especially on Railyard, Creature Workshop, High Sea's Fortress, Liquid Fire and Steel Beast. I have been able to do it a handful of times on Solo, but that took dozens of runs on a single map before I was able to memorize enemy spawn patterns. If you are also going for holding the secret boss until the end, then that is a sigh that you are an amazing player. One of the easiest maps to 150 combo is Rooftop Mission due to it's small size and use of zombies, just be sure to watch out for the Ubistvo and Napad enemies! Catacombs is also pretty easy to 150 combo as enemies will funnel to you and the traps help your combo.
When facing a zombie apocalypse, don't join up with a group. Why? Because you'll end up blowing your own head off due to all the pointless drama caused within.
The only maps I've ever gotten a 150 combo on or 150 enemies killed (either or) in solo are Catacombs and Rooftop Mission. The former is difficult due to the larger size and relative non-openness of the stage, but manageable. The latter is quite simple due to the stage's small size.
J'avo maps are tougher due to the semi-random mutations.
It took me a while to finally get a 150 on Urban Chaos and few more days to hold that pain in the... Napad on Urban Chaos on solo. UC solo boss holding is something that I really don't want to do again.
