I think they did a great job with those new mobs. You have to adjust your tactics to fight them and that's probably why sometimes they feel so OP: just standing there and shooting won't help you

I've been really enjoying it so far, but I have to admit the corrupter can be a bit of a bullet sponge sometimes

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.

It seems pretty good so far. The boots are a nice touch, and the new enemy types are keeping the game fresh. The mission control dude has been repeating himself on some missions. Hopefully they fix that soon.

It's been great so far! Lots of new voice lines! I'm conflicted on the stingtail. Cool enemy but I wish it would have a glowing spot so you could see it before it snipes you in the dark. At least the mactera grabber has to get in melee range, stingtail can be anywhere. Thankfully the squeaky toy noise will put you on high alert.

I feel like the Spreader is tough but fair. The corruptor is fun, but the difficulty of it largely depends on terrain complexity.
