Resident Evil: Operation Raccoon City

: You must be signed into the Sony Entertainment Network to unlock this trophy.
Maximum Players Needed to Boost: At least 2

This is a Versus Mode trophy and can be done either in "Public" or "Private" matches. A self-explanatory trophy, just simply kill over 50 human opponents in any Versus Mode matches type. You can keep track of this in the "Records" found at the main menu screen and then scroll over to the "Versus" tab to view stats. You can do this without boosting at all as people are currently active online, however, if you're boosting almost all your Versus Mode trophies in Private matches, then this will naturally unlock.
