Rock the game IS hard, especially if you play it solo and as a straight combat game. Solo? You have to avoid fights in the open and use a lotta stealth and tactics. Scurry around like a rat in a world full of cats until you have the ammo and weapons (and levels) to strike! That’s what makes it fun.
If you play co-op you have a lot more opportunities for straight combat. Especially as you specialize skills and get some of the Apex skills to help the group.
I plan on watching Tom’s stream, but the world is sorta weirdly empty (until they find you --or you find them) and has a certain samee-ness to some things (like houses, etc). I have noticed as I progressed that home layouts, weapons, loot etc are different and get better.
Plus the robots have weaknesses and when you figure them out it does get easier.
