I'm over here, minding my own business, when BLAM! Out of nowhere that creepy twit robot Benedict patches into my network here. Seriously, I could've been naked or something!
That dillbot wanted me to flag you down because there's a Vex problem on the fish face ship. Apparently there's a big bad Vex Mind that's clogging up the ship's works worse than a middle-aged male suffering prostate issues.
Would you go help Calus with his stupid plumbing problem so I can get that psycho sweeperbot out of my head?!
An alternate method for completing the jumping puzzle at the beginning. Neither is "wrong," it's all a matter of preference.
Defenders grab 1st heads, run them to where the elemental charges are facing. Charge heads & kill adds until damage phase.
Runners grab 2nd heads, split up if necessary to charge necessary elements. Stick together whenever possible. When ready to shoot elemental charges, cross shoot (L shoots R charge) for best accuracy.
During damage phase DPS the boss on the nose. High impact like Whisper of the Worm or Sleeper Simulant work great. Well of Radiance, empowering rifts (w/Lunafaction boots better) help.
There are 6 crits (2 each side & 2 on back) which need to be destroyed. Pop 2 between rounds to disable the wipe mechanic. Argos does not take significant damage during this phase, so focus on crits together instead of DPS.
When the crits are popped, work on destroying Argos' cannons on each upper arm. This will prevent him from hitting you with his Void bombs while you pop his shield next round. Sustained steady fire (trace or auto rifles) to the crit will pop them in no time. If you are getting "white" numbers instead of "yellow" ones, reposition and fire when you can hit the crit directly.
NOTE: Whisper of the Worm is extremely effective here! Not only does it do incredible damage during the damage phase (constant source of ammo by hitting it on the nose, too), but it only takes a couple of shots from a WotW to pop a crit.
