Game is finished. God were the last 2 missions ever horrible. Bullet sponge boss battles. So annoying. Would have been a lot easier had I levelled up my health pool and weapons more but regardless I got the job done. Almost gave up on the final battle but gave it one last shot before going out to scavenge for more upgrades. Thank god I was able to kite that big asshole around long enough to take him out! Sadly though I barely even knew his character so it didn't have the satisfying end that offing the two twins did. Oh well c'est la vie.
