The code for Resident Evil 5's versus mode feature is small, tiny for two competitive online modes. Seeing a 1.8MB file for Xbox 360 owners and a 351KB download on the PS3 led to discussion that the versus mode was not a new feature with its own budget as a Capcom previously commented.
Capcom Vice President Christian Svensson stands his ground and says, "Keys are 100K or less. It is not a key. We have said in the past, it uses assets from the disc (like levels, models, audio, etc.) but the code is new and does not exist on the disc."
