When hearing the bugs people were running into it reminded me of some of the old ps2 bugs, then when I played the game it was just the console loading screen and menus, with the wonkyness that would come from a direct port. So after a little time playing I got curious and tried the old ps2 Regerating Ammo cheat and it worked. And I laughed a lot.

Regerating Ammo
Pause while playing offline and input UP, DOWN, LEFT, DOWN, DOWN, LEFT, DOWN, DOWN, LEFT, DOWN, DOWN, DOWN, LEFT, RIGHT. A chirp similar to the one heard when pausing will occur. Your ammo counter will go down, but will refill instantly when reloading.

Cheat Player Invulnerability
While playing in offline mode, pause the game and input UP, UP, UP, LEFT, DOWN, DOWN, DOWN, LEFT, UP, UP, UP, LEFT, RIGHT. A sound similar to the effect you hear when you pause the game will occur. This code cannot be turned off until you shut off your game system.

Cheat Slow-Mo Sounds
While playing, pause the game and input UP, UP, UP, LEFT, UP, DOWN, UP, UP, LEFT, DOWN, DOWN, DOWN, LEFT, UP, DOWN, DOWN, LEFT, RIGHT. The code turns off only when your game system is rebooted and may only be entered in Rise of an Empire mode.

added cheats {1}

Cheat Alternate Soldiers, Down, Down, Down, Up, Up, Left, Down, Down, Down, Down, Down, Left, Up, Up, Up, Left, Right
it makes most of the solders look like the long distance low rezz version

Cheat Funny Wampas Up, Down, Left, Down, Left, Right [ you need to be in a hunt map with the wampas for this one to be activated] it adds cartoon affects when wampas hit things

{}

most of these you need to be in instant action to use, but then you can go to a campane or galactic conquest. there are more and I bet more people will make better guides, but I thought I would get this out so people will know

edit / added info 1 (it seems they can be activated in galactic conquest and needs to be activated after every match unlike in the PS2 version.)

edit / added info 2 (cheats don't stop any thing, from in game awards too steam achievements, though I still haven't tested if they work in the multi player, in the console version when activated they stay activated like in the pc version, but in the pc version there typed in the instant action menu, while in the console version there activated in an offline map, so not galactic conquest or multi player, but given they can be activated in galactic conquest here, it makes me wonder)

edit / added info 3] This is just a copped comment I left and put here to be found easier cuz it had some findings
(The cheats usually work first time for me but they deactivate between matches, and I'm not surprised they don't work in multiplayer, but am still surprised they work in galactic conquest, the way it was set up in the old versions cheats were only suppose to be able to be activated in training and instant action, but then they would stay on, unless... the... the internet... was on, on your console... that makes me wonder if the internet was off if they would stay on, then you could go else where, turn the internet back on and have one round with the cheats on? But still even if it worked better to not try using it in multiplayer, could get in trouble.)

Again, even if there was a way to put the cheats in multiplayer mode, please don't, I know I'm very curious considering the over-sites by the Devs, but it's not fair to the other player, and you'll probably get caught in the long term.

also ( I mostly just use the ammo cheat cuz it feels strange to run out of ammo in starwars. )
