Id say this combining together some other`s suggestions: Up: Cycle through primaries Left: Cycle through secondaries Right: Cycle through heavies Down: Consumable While pressing select (with your ghost on the hand): Up, Left, Right, Down: emotes Now the fun part. While pressing R3: Up: Primary synth Left: Secondary synth Right: Heavy synth Down: Mini map Wouldn`t that be great? PD: Took this from another forum, got the acceptance from the creator of the post. PD2: Bungie PLEASE take a look at this! When I open my inventory on PS3 it takes too long to load and it`s so hard to switch weapons (I`m on a 50mb internet connection). It would be faster if we at least switch weapons with the d-pad.
