Dark Sector

You'll have access to the Protecta, and the VX Carbine. The Protecta is a pretty powerful shotgun, and is much better than what the guards have but my suggestion is waiting to buy the shotgun pistol a little later on. The VX Carbine is a sniper rifle that uses magnum ammo, but I didn't find it all that useful. You should save your money for the shotgun pistol and the best assault rifle. You'll encounter the second jackal on this level, but this time you'll be able to hijack it. Use your glaive to ignite the barrels on the truck on fire and burn the black shield thing that's guarding the electric panel. Charge up with electricity and hit the Jackal, then quickly run around behind it and hit "B" . You'll hijack it, getting the achievement and also avoid an unnecessary fight.
