The Ion Torpedo is one of the Star Cards you can acquire relatively early in Star Wars Battlefront. It essentially acts as a missile launcher, though some players might be confused as to why they can’t seem to fire the weapon at times. Here’s the thing about the Ion Torpedo that the game doesn’t exactly make clear right off the bat: you can’t use it against human enemies, you can only use it against vehicles and stationary weapons.
This means that the Ion Torpedo will only lock on to vehicles like the AT-AT, AT-ST, speeders, and stationary weapons like turrets. You’ll find that when you aim it at human enemies, the Torpedo will not lock on, and you won’t be able to fire the weapon at all. To use the Ion Torpedo, simply aim it at any vehicle, wait for the small white square to pop up on your screen, signaling that you have locked on to a target, and then fire.
So the next time you boot up the game, make sure to swap out the Ion Torpedo Star Card for something more useful if you’re playing modes like Hero Hunt or Heroes vs. Villains. If you’re playing Walker Assault, however, the Ion Torpedo will prove to be very handy, especially if you’re on the side of the Rebels.
