Surface more player data in game
In previous Killzone games, a player could see their accuracy and playtime on individual weapon's categorizes (such as rifle or shotgun). This, and a player's highest overall kill streak should be seen under the in game stats. Total play time is available on the official site, under profile, but it isn't surfaced in game. I know some games, like CoD, surface heat maps. Any other interesting data points you're recording would be great to see. Also a leaderboard with worldwide and friend filters would be appreciated.
