I consider the gameplay to be good, some puzzles could use a little more info but overall good puzzle design. The reason for my negative review is how piss poor the optimization for such a simple game is.... no matter what graphical settings I chose I consistently had extreme frame drops/stutters. The game was nearly unplayable due to the issues and I wouldn't recommend playing the game unless you just really want to finish the series.

Edit: After completing the game I now recommend the game even less than before, the performance was even worse in some areas and a handful of puzzles had good ideas but overall had poor execution making them very difficult to solve without extra insight... Overall still don't recommend the game unless you just need to finish the series

Cons
- Gameplay extremely unclear to what is going on
- Terrible hit reg and servers making gunfights super inconsistent
- PvE mode used to get better weapons for PvP mode. (guns will be half as good as opponents unless you play pve)
- Poor map design
- Extremely over-tuned aim assist

Pros
- Nice movement

Overall a very creative game that took a unique approach to a singe-player shooter
pros
-very cool environments
-nice mechanics (shooting and movement)
-decent humor and story

cons
-poor optimization
-no FOV slider
-very buggy, I managed to do a mission backwards and had to relaunch the game to fix it, managed to get out of the map and get stuck in multiple places (non game breaking)
-some dialogue/characters get annoying
-highest difficulty isn't difficult at all (not a huge deal)
