There are a total of nine militia Watchtowers located on Founders’ Island and they can be found in the following locations:

Founders’ Island Watch Tower 01:

Description: This Tower is actually disarmed during the main storyline and will trigger the Most Wanted mission.

Founders’ Island Watch Tower 02:

Map co-ordinates: (2879, 1598)

Description: By the western end of Salvation Bridge, directly below the monorail tracks.

This area consists of three armed Soldiers and a Boa Drone and is actually ridiculously easy if you know how to approach it. If you land on top of the room with the guards, you can actually see through the chain-linked wire floor to see the enemies within. Use the Remote Hacking Device on the Drone controller and then use the Boa Drone to knock them all out for a quick clear of the area.

Once you have eliminated all of the enemies you can then find the command console and use your Explosive Gel on it to blow it up.

Founders’ Island Watch Tower 03:

Map co-ordinates: (2614, 1586)

Description: Otisburg – on top of a building directly north of the road leading north from Port Adams.

This watchtower is essentially a small predator area in which we need to stalk and eliminate six Soldiers (one with a Detective Mode Detector) and a Medic. The rooftop itself has some cables strung overhead for a nice view of the enemies below, several weak walls that we can exploit for Explosive Gel takedowns, plenty of walls for corner takedowns and a weapon crate that we can sabotage with the Disruptor before using the Voice Synthesizer to have guards inspect it.

We’ll want to identify and eliminate the Medic first before taking out the other enemies in the immediate area.

Once you have eliminated all of the enemies you can then find the command console and use your Explosive Gel on it to blow it up.

Founders’ Island Watch Tower 04:

Map co-ordinates: (2410, 1667)

Description: Drescher – On top of the building under construction across the road to the north of the Gotham Stock Exchange Building.

This is easily the hardest watchtower that we’ll tackle in the entire game. This rooftop has not one, not two but four Minigunners patrolling the area along with two Medics and two Soldiers equipped with camouflage armour (which makes them invisible in Detective Mode).

The rooftop itself has a wealth of stealth options including multiple weak walls, plenty of corners, high up girders on the inside and a network of floor vents. It also features multiple floors so that you make a quick escape or scout the area from multiple angles.

We’ll want to take out the Medics first of all, before attempting to locate the Soldiers with the camouflage gear and then finally turning out attention to the Minigunners. When it is down to just Batman and the Minigunners you’ll want to wait for one to be well away from the others before attempting to take him down and then quickly retreating before the backup arrives. Rinse and repeat until they are all down for the count.

Once you have eliminated all of the enemies you can then find the command console and use your Explosive Gel on it to blow it up.

Founders’ Island Watch Tower 05:

Map co-ordinates: (2452, 1333)

Description: Ryker Heights – Just south of the large circular road area on the world map. On top of the building with the half constructed railway bridge leading into it.

As with many of the other smaller-sized watchtowers you’ll encounter, this one consists of a medium sized group of enemies that we’ll need to subdue. The forces guarding the roadblock include seven soldiers (two with melee weapons) and a Brute. It’s a good idea to prepare for the fight by using the Disruptor to disable the enemy weapon crates in the area. If you can lead into the fight with a Fear Multi-Takedown and use it to eliminate 3-5 enemies as soon as you begin, the remaining hostiles will be much easier to dispatch.

Once you have eliminated all of the enemies you can then find the command console and use your Explosive Gel on it to blow it up.

Founders’ Island Watch Tower 06:

Map co-ordinates: (2269, 1904)

Description: Drescher – By the southern part of Perdition Bridge.

This is another of the very small rooftop fight watchtowers. The contingent of enemies patrolling this one are made up of seven Soldiers (one of whom has a gun). Prepare for the fight by using the Disruptor to disable the enemy weapon before dropping in and taking all of the enemies down.

Once you have eliminated all of the enemies you can then find the command console and use your Explosive Gel on it to blow it up.

Founders’ Island Watch Tower 07:

Map co-ordinates: (2613, 1385)

Description: Otisburg – In the southwest corner of the area on a small building’s rooftop near the water. Just north of the entrance to Port Adams.

This watch tower is comprised of a very small enclosure guarded by a group of enemies whom we’ll obviously need to knock out. The enemies guarding this small rooftop include three Soldiers, three Combat Experts and two Medics. Before approaching the fight we will need to use the Remote Hacking Device to blind the Sentry Turret overlooking the combat area.

During the fight you’ll want to focus on downing the Medics as soon as possible before finally dealing with the other enemies.

Once you have eliminated all of the enemies you can then find the command console and use your Explosive Gel on it to blow it up.

Founders’ Island Watch Tower 08:

Map co-ordinates: (2792, 1857)

Description: Drescher – By the northern end of Penitence Bridge.

This is another of the very small rooftop fight watchtowers. The contingent of enemies patrolling this one are made up of four Soldiers and two Combat Experts. If possible, you should try to start the fight by using a Fear Multi-Takedown and use it to dispatch as many enemies as possible (preferably Combat Experts though!) before clearing out the remaining enemies.

Once you have eliminated all of the enemies you can then find the command console and use your Explosive Gel on it to blow it up.

Founders’ Island Watch Tower 09:

Map co-ordinates: (2536, 2071)

Description: Drescher - Below the broken bridge to the north of Penitence bridge. At ground level beneath the building with the large radio antenna and rotating wall mounted turrets.

This is an unusual watchtower in that all of the enemies that we need to eliminate are below the building in question, at ground level. Having said that it’s really not all that unique as the general small zone combat scenario comes into play for this watchtower as well. There are seven Soldiers (two with shields) and two Medics to deal with here.

Engage in combat with the enemies ensuring that you get rid of the Medics first before focusing on the other opponents.

Once you have eliminated all of the enemies you can then find the command console and use your Explosive Gel on it to blow it up.

For clearing all 21 towers you’ll earn the achievement/trophy ‘Gates of Gotham’ .
