That and maybe less "Bullet Sponge Combat"...
Difficulty shouldn't be "Add more HP and give less ammo". It should be "Aliens adapt to how you play and look to outsmart you.
IE: The movie, Aliens. If frontal assault don't work, time to use vents, ceilings, and floor panels.
I'm sorry but.. An "Aliens" game shouldn't have Infinity Ammo Boxes, and MOBA Abilities. There's nothing scary/tense about kiting Xenos while spamming 2 buttons and shooting them in the head for 10 minutes or more.
Especially when, yaknow, those things are meant to be faster than humans, how can we kite them? And Melee? Meleeing an Xeno should be a death sentence.
And making Aliens into a "Grinding" game is... Well, it's a disservice to the title of "Aliens". I think instead of learning from their "Arcade" version of the franchise, they should look at RoN, in that you fight humans but it's actually tense and outright bonkers at times. If you turned the terrorists into Xenomorphs with really good AI, then you'll have a brutal Aliens game, which is where Aliens: Colonial Marines failed.
Too much Pew Pew Bullet Sponge = Not tense and just a chore. Aliens should be tense, deadly, grounded, and gripping.
