That dude. UGH.
After you aggro him, run back down the steps and jump off the cliff into the water below. Wait about 30 seconds then jump your way back up....and stealth kill the fucker.
Don't feel bad about the cheese, you run into him again later and he has two health bars. By then you'll...
Game is OK, I think I've dropped maybe 15 hours of playtime on it. I'm going to let it cook for awhile...maybe see what state the game is in 6 months or so.
If your expecting a 'metroidvania'...this aint it. Think a more classic castlevania with randomized levels and more modern-ish combat...
I noticed in my last playthrough that turrets and operators (even destroyed ones) give a decent amount of mineral materials. Spare parts do as well, so once are all over the place late game you can get quite a stash
There are still a decent amount of recent SP games that have really grabbed me. Dark Souls 3, Dishonored 2, and Witcher 3 come to mind.
I do find myself dropping games half way through (Far Cry 4, Metal Gear V, Batman Arkham Knight being recent casualties), and that sure the hell never happened...
Not so 'random' at all then
Here's my list
SPACE MOTH DX
VAMPIRE OF THE SANDS
CORPORATE LIFESTYLE SIMULATOR
THREE DEAD ZED
HUNTSMAN THE ORPHANAGE
Exactly same games. That's pretty horseshit.
