I have noticed that its much more difficult when you get a lot of the new mobs.
The corrupter is a pain to fight on uneven terrain, which is most caves.
The septic spitter creates painful hazards, but is at least easy to identify and kill.
I’ve seen the stingtail down so many people by moving them out of position repeatedly, so I’ve found i need to protect teamates it’s targeting.
I love the jet boots, especially as gunner, but even as scout its useful. I just wish I’d see them more.
Indeed it was more difficult than S3 but kinda fits the story line I think? Unlike S3, you really have to keep your distance from the mobs. I died many times right after I got “entangled” by the rockpox (where you have to AD to unstuck) during my first mission on S4.
Jet boots + low gravity = endless fun. If you keep tapping space you can maintain your momentum.
