10 Missable Video Game Items That Cost You 100%

10. Research - BioShock 2

Aside from its focus on storytelling, another great selling point of the BioShock games is the combat that marries firearms, melee and even something akin to spell-casting. By equipping tonics, players are able to max out their skills and fling fire, ice and lightning at the various nasties that come their way.

Aside from all the ways to dish out punishment, BioShock and BioShock 2 had the research camera which implored players to take a few photos of every new Splicer they came into contact with.

Maxing out research on enemies is important for three reasons. Firstly, it is quite simply tied to 100%. Secondly, researching enemies offers you bonuses against them. Finally, the final piece of research on many foes gives the player certain exclusive tonics.

However, if you don’t get to capturing wonderful memories of your time in Rapture with your insane buddies as soon as you’re able, it’s entirely possible to miss your chance. As you progress throughout BioShock 2, certain enemies no longer spawn and it’s impossible to get the research you need.

It seems like a simple thing but the camera and research element of the game is truly completely optional… unless, of course, you want to feel like you’ve fully accomplished the game, in which case you better get snap-happy.
