It is impossible to obtain a jet pack in Halo 2 without modifying the game istelf.
unfortunately without mods, it cannot be unlocked :L
play a forge created game that has the upgrades placed in the map, or change the game settings in a custom game.
There is no grunt ability. Just - Sprint, Hologram, Evade, Jetpack, Invisibility, and Armour Lock.
Yes
You can get into vehicles that fly. For example, the Banshee.
You cant, not unless you mod! Your welcome! C:
you dont you just find them on a map or pick them with the armor abilities.
There are no cheats just go to game options and general then weapons and something and turn unlimited amo on
Halo Reach is better because you get to customize your own character and you get special get special abilities.
To use the jetpack you need the armour upgrade usually seen as a white hologram in an open case on the floor in campaign. Then press and hold the left bumper for Xbox (don't know about other platforms) and you should be in the air. MULTIPLAYER on multiplayer just select the class that says ranger or the one that has the spartan with a jetpack on.
There are no cheat codes for Halo: Reach. However, in forge, custom games and firefight, under the game options menu, stats and abilities of players can be modified, as they could in Halo 3 and ODST. In that menu you can turn damage resistance to 'Incincible'.
You can't, but you might be able to if you mod. But there's a fat chance you'll be banned or reset.
