Melee actually hurts the Aliens!?! Wow... That's really, really lame. I thought it just stunned and halted them, or pushed them back.
Man, they really turned the Aliens into weak, weak, weak cannon fodder in this one. Either that or lumbering lobotomized weightlifters with an affinity to flex and roar.
Yeah, I know, it's going for arcade fun, but you lose all the character of the franchise when you can literally push and punch a xeno to death, not only that you can also and/or outrun them and/or outmanouver them with quite ease. Zero fear.
I've watched a few video of people playing the game on Extreme difficulty and Insane difficulty, and although the players behave less cocky and super hero like and often don't get very far, the problem still remains: Enemies are only dangerous if there are a looottt of them and they manage to swamp you, or cornering you in the case your squadmates have fallen already. I feel like the standard Runner should be like the Prowler with the death splash of a Burster - that would make things a lot more interesting (...and realistic).
Anyways, watching those Extreme & Insane difficulty gameplay videos I can't for the love of god understand why anyone would ever choose to play the game on Standard or Intense the second time you play through the campaign or when playing it on horde mode.
