Explosive Devices

[Inner Sight]

Trying to get the full ending. At the moment all I have left are two explosive devices to find and I'll be done with all of the "Most Wanted" missions.

Thing is running around blindly to just stumble onto these bombs got boring when I kept finding nothing. Any chance there's a place I can go or a thing I can do that makes them show up on my map before I already found them?

The final mines spawn here:
Bleake Island: abandoned canal separating Cauldron and Panessa Studios.
Miagani Island: avenue intersection between Bank and Wayne Tower throughway underpasses.
Founders Island: Port Adams.

Honestly I don't even know if it's the final ones that appeared. I avoided most of the car stuff until the end. Thank you though. Having a specific place to check has a lot better odds of finding a bomb than aimless vrooming.

Check your Most Wanted: Campaign for Disarmament progress from the mission wheel, that will tell you from which island you're missing. All 14 mine locations as follows:

Bleake Island, 4: intial post-Clock Tower drone drop. Falcone trainyard in Cauldron near Riddler and Penguin hideouts. Chinatown roundabout intersection near Batmobile Weapons Diagnostics. Abandoned canal separating Cauldron and Panessa Studios.

Miagani Island, 5: Lacey's department store between Grand Avenue intersection and Grand Avenue Station. Lower level on-ramp intersection near Miagani Gardens and Elliot Memorial Hospital. Miagani Gardens under red tower East which spawns the Natural Selection AR challenge map. Kingston main intersection after crossing Mercy Bridge from Bleake Island. Intersection between Bank and Wayne Tower underpass tunnels.

Founders Island, 5: Otisburg lower intersection after crossing Penitence Bridge from Elliot Memorial Hospital. Ryker Heights street level under raised Urbarail Station firefighter rescue and above firefighter Lozar's sublevel location. Ryker Heights sublevel near Penguin's Grinning Fishmonger hideout and firefighter Lozar's sublevel location which spawns Slumdog Billionaire AR challenge map. Perdition Bridge landing after crossing from Bleake Island. Port Adams entrance.
