The BioShock 2: Sinclair Solutions Test Pack
's two new characters offer another view of Rapture before the fall. Oscar Calraca is Rapture's billionaire playboy with a soft spot for cats. Louie McGraff represents Rapture's criminal element. He's a smuggler who managed to smuggle himself into Rapture. Both characters' backstories are filled out via audio logs, though the actual value is debatable. Their stories are interesting (especially Oscar's), but really don't matter in the long run. It's cool the characters are fleshed out, but it doesn't enhance the experience.
The bigger deal for players, beyond two new faces in matches, is the increased level cap. The cap also brings a few new player rewards, mainly new masks for characters and access to twenty new multiplayer trials. The cap increase is welcome, but the rewards are a bit of a letdown. Going from 2 - 40 you at least got new weapons, tonics and upgrades. Here you just get masks and bragging rights. This would have been a good use for fleshing out the third weapon upgrade slot, but those are available from the start.
The twenty new multiplayer trials (a sort of meta-game going on throughout multiplayer matches) are fun if you like completing them. Nearly all relate to the new weapon upgrades, like extended clips and new bolts for the crossbow. The additions are another major plus for multiplayer and almost worth the full price of the download. The new upgrades are a blast and have changed up a few of the tactics that had become so predominant in multiplayer matches.
