*This guide is specifically for the normal and prestige version of The Arms Dealer during the week of October 31- November 7 as modifiers and enemies change.
Prism: Attack matching the element that appears on the bottom left deals increase damage. All other elements deal less; does not affect incoming damage nor Kinetic weapons.
Timewarp: Kill enemies to obtain more time. Lesser enemies give +2 seconds while tougher enemies will give +7 seconds.
Time: 7 mins on Prestige Mode; 11 mins on Normal Mode
Enemies: Cabal (Psions and Incendiors) ; Fallen (Vandal and Captain)
As soon as the screen loads, head left and toss grenades towards the group of Cabal. Take out the 2 shielded enemies with Void weapons and grenades. Focus on the Fallen enemies now using arc weapons and hack the terminal to the left of the group once finished.
Enemies: Cabal (Incendior, Psion, Honored Legionary, Honored Phalanx, War Beast, Unsanctioned Blaster, and Exiled Launcher) ; Fallen (Vandal, Resilient Captain, and Unyielding Servitor)
After hacking the terminal a door will open, head through it and prepare for a fight. There will be several enemies you must defeat. Take out the Fallen that emerge from the left side first then focus on the Cabal. After the enemies are clear, have one person pick up the round sphere and take it to the marked location. Everyone else should run towards the lower area once there, avoid the obvious path and instead, head up the right side climbing up a ledge. The person with the charge should deposit it while getting cover fire by their teammates. Once the charge is deposited, eliminate the boss enemy with the prism enhance element. Shoot down the Thresher then focus on the Fallen enemies blocking your path to the inside of the base.
Enemies: Fallen (Dreg, Vandal, and Shank)
Once those boss enemies are done for, run up the path and inside the base. Bypass all the enemies you’ll find and take the entrance to your right. Continue running up the inclined interior of the base until you reach an open gate. Summon your sparrow and head north west towards a orange glow tunnel and a sloped piston. Climb the piston, summon your sparrow and bypass the enemies while heading left towards the base. Follow the only path inside until you see a giant tank.
Enemies: Cabal (War Beast, Honored War Beast, Legionary, Phalanx, Goliath Tank, and Unsanctioned Blaster)
On the right is a platform which must be hacked, be wary of the three enemies guarding it. Next, head straight, then make a left towards the red draped platform to climb it to hack the second terminal. This will spawn an elite enemy, Unsanctioned Blaster, take him out and a large tank to progress the mission. Toss a grenade to eliminate the War Beasts that will spawn from the newly open door. Enter through the door and follow the path until you reach the end.
Enemies: Cabal (Legionary, Honored Centurion, Volcanic Scorpius, and Unsanctioned Blaster) ; Fallen (Vandal, Resilient Captain, and Unyielding Servitor)
Open the door using the terminal on the right. (This takes about 20 seconds) Have one person take the upper route while the other two take the lower route (or vice versa). Take out the turrets (Volcanic Scorpius) first then focus on the rest. Players will have Fallen and Cabal to take down. At the end of the hanger will be a lift, eliminate the last enemies and prepare for the boss.
Enemies: Cabal (Legionary, Psions, Centurion, Honored Phalanx, and Volcanic Scorpius)
Weak Points: Head
While the lift ascends you have time to shoot the boss while he does the same thing. Head towards the left ledge and take out more of those turrets (Volcanic Scorpius). Once the boss’s health has gone down by 1/3, he will retreat and summon mob enemies. Take them out and have someone grab solar charge (sphere) and deposit it in the proper location. The boss will be able to be damage once more. Repeat taking out the turrets, damaging the boss, picking and depositing the solar charge. It shouldn’t take long to defeat Bracus Zahn.
