In Deathloop, there are two types of missions players track. Firstly, there are the Visionary Leads, the main mission quests that help perfectly line up the visionaries to kill them all in one run. Then, there is Arsenal Leads. These quests focus more on helping the player to get better gear.
While the basic concept of the majority of Arsenal Leads is to kill off the visionaries and collect their slabs, there are also four different side quests that players will have to learn about as Deathloop goes along. If they go through with them, Colt could end up having a really nice weapon added to his loadout. Here's how to find and complete each of these quests.
4 All Night Long
For this side quest, players will need to break into Frank's club in the morning. Players can go through the front door, but they will need to attach a class pass. There are a few hidden entrances hidden around the building that players can access if need be.
The bottom line for this mission is to kill Frank. He will likely be locked in his studio after he realizes Colt is around. Getting around the building is easy with the class pass, but can be a lot harder without one. Luckily, with the help of Colt's hacking device, players should be able to navigate through most of the doors. When facing the studio, players will need to find a panel to the left and hack into it in order to open up the door.
After getting rid of Frank, as well as some of the Eternalists that have gathered to stop Colt from harming him, Frank's legendary weapon, the Constancy Automatic, will be lying nearby either on the ground or on a table. The gun can be reloaded and fired at the same time. It also slows advancing enemies down.
3 In This Together
To complete this quest, head to The Complex in the afternoon, where there is a nice duel-pistol set waiting for Colt. These pistols turn into an SMG and also slow enemies down when hit. Players should head out of the tunnels and towards the large explosion that they will hear soon after leaving.
The side quest requires Colt to explore the Ordinance Depot. When players find the room where the pistols are, they will need to find four batteries that will allow Colt to hit a button and open the door. Luckily, exploring the facility will easily lead to hidden batteries being found.
One battery can be found in a lamp just outside the room. From there, players can find a few other lamps around the facility that may have batteries in them. There also may be a turret that players can gain access to that has a working battery. Keep in mind that these batteries must be working, because otherwise, the mission may not be able to be completed.
2 Keep On Giving
When entering Updaam in the afternoon, an eternalist will be talking over the loudspeaker with a message for Colt. She will say there is a gift in front of the Dorsey Mansion for him. However, don't be fooled by this, as the gift will cause a firing squad to jump on Colt.
This mission can be completed in a few ways. Players can use the Aether slab to go invisible and open up the gift, although doing so will cause the individual to accuse Colt of cheating. Regardless, there won't be a nice reward inside (only a low-level trinket) as the goal was to start shooting Colt at that moment.
On the other hand, the gift can be avoided altogether. Enter the building that has a direct view of the gift from a window. In there, players can kill the three eternalists staring out the window. The one nearest the window, supposedly the person who was talking, will have the legendary weapon: the Sepulchra Breteira. This sniper rifle shoots farther and is more accurate. There were also be a ton of trinkets to collect.
1 Super Shifty
This side quest will take quite a bit to achieve, but it may be worth it depending on how much players may want the Heritage Gun. To get the details of this quest, head to the building that has the Fathoms of Lament hanging on it, while a voiceover of Charlie talks about the challenge.
On the way there, players will spot a few eternalists staring at a strange box. After some time, this box will explode, killing these two eternalists. This will indicate to players what they will need to search for ahead of visiting the building.
Inside, there is a map that will note a bunch of boxes that are rigged with explosives. The goal is to open all of these before the end of the loop. Doing so will unlock the room right near the map that will have a few more tests before rewarding Colt with the Heritage Gun, a gun that transforms between rifle and shotgun.
