The game was completed at 114.2%, on an impossible difficulty level (except for co-op missions). All costumes, all weapon parts (including MKII parts), all modification chains are open; collected all artifacts, all audio recordings/logs, all weapon plans.

P.S. — To be honest, I still don’t understand how I managed to get more than 100 percent in the game without going through co-op. missions, open all the goodies O_o
