Is it possible to play this solo?
Yes, you can play it solo.
Looking at a lot of the PC reviews and I'm disappointed in them. Mainly because I also reviewed the PC version and they haven't even mentioned how the game's performance, the features such as DLSS and Reflex (which is so good). The game isn't bad, but it isn't a Left 4 Dead 3, and it was never meant to be that way. It's totally playable, it does have some rough spots and it is very grindy as you have to level up each operator individually. But playing in a group is rewarding and fun, as long as you play as a team.
Game balancing is definitely an issue as many have said. It's definitely overturned and that needs to be addressed. It's like the game has a hard-on for you most of the times. Still, the game is serviceable and as long as Ubisoft is paying attention to the reviews and feedback, I'm sure they'll adjust it.
Tossing in our review as well.
