It isn't. At least, not until the last level, where things got a bit too hard for me. There's a DLC that's set in a theme park that I quite liked. The other DLC I bounced off.I bought The Surge - Augmented Edition. It's dirt cheap on Steam right now, and I was curious about it. I guess it's like a sci-fi Dark Souls? I've seen some claim it's even harder than FromSoft's games so idk.
There's a difficulty spike at the first boss, but if even I can roam around the beginning areas over and over trying to git gud enough to beat him, then I imagine you won't have any issues.
