No you can't.
Sorry there arn't any, The only skulls are in "Halo 3" Which are used in "Halo 3 O.D.S.T."
The banshee is a flying machine in Halo Reach used to kill Spartans in multiplayer.
There are none. How ever, there are skulls that once collected can be used to give an advantage to the player.
any weapons can be used even dual weapons
You can use that during campaign scoring mode along with other skulls to rack up points more easily... if they are not silver skulls. silver skulls are used to just have fun during campaign mode.
you can use any gun that u have used in the mission mode
It is impossible on the Xbox but it can be used through maps in Halo Custom Edition(on PC). Halo Custom Edition is a freeware but it requires Halo PC which is not free.
It is when you destroy a vehicle with 3 or more players in it on campaign or ranked multiplayer
It is not in halo combat evolved proper, but you can probably get mods with a gravity hammer in it for halo custom edition. It is in halo 2 used by Tartarus but you cannot wield it. In halo 3 you can wield it i multiplayer and campaign. I have no idea about halo odst but it was not in the list of weapons not in odst so I imagine it is in there.
The skulls are used to activate cheat codes, such as recovering health when you punch an enemy. You activate these by pressing X at the mission selection menu.
Halo ce or custom edition is a version of halo combat evolved online allowing player created maps to be used in battles online you can get this version of halo ce from halomaps.org or .com i cant remember which one. Once there go to halo ce maps, then search the page for halo ce download. ---__________________________________________________________________-Halo 1 free: http://www.megaupload.com/?d=7RF9TKB4Halo Ce free: http://www.youtube.com/watch?v=uYdtdwokudI
