- The changes that were made by InterventoR through B&T Expanded Enemies to enemy Custodian weapon damage values and Custodian stats have been carried over to Mod Jam.

- The Sealed Undersuit ability has been removed from the Custodian Armors that it was on. In its place is the Custodian Armor Immunities ability (template name SealedUndersuit_LW), which has been granted to ALL Custodians rather than just the Exalted ones. It grants immunity to poison, Chryssalid poison, Elerium poison, acid, fire, frost, Viper Bind, and knockback.

- The Custodian Pistol, both Rifles, both Shotguns, and the Advent Courier's SMG now use the same range tables as the equivalent XCOM weapons. The Exalted Custodian Pistol and Flechette Gun retain their unique range table, however.

- On top of InterventoR's changes, the Custodian Master's rifle now has 5 armor pierce. There is a good reason for this that you'll find out down below.

- The Custodian Mk2 now has the Impulse (F_Momentum from Favid's Extended Perk Pack) ability, giving them +10 each to Aim and Crit Chance when they attack after moving.

- Regular Custodians now wear Automend Weave, but have -2 natural armor and +1 natural mobility to normalize their stats. This will allow them to regenerate 1 shredded armor per turn, up to 4 total per battle.

- The Exalted Custodian Grandmaster's rifle now has the Shiver (30% chance to inflict Bitterfrost with any landed shot with the weapon), and Running On Empty (automatically reloads one ammo into the weapon if the magazine is empty and a movement action is made) abilities, from Mitzruti's Perk Pack DLC Extention and Mitzruti's Perk Pack respectively.


- The Metion Battlesuit's HP has been buffed in order to make it a more meaningful upgrade from Titan Armor; it now grants +15 HP. It also now grants the Custodian Armor Immunities ability. Metion Shield defense debuff has been decreased to -30. Metion Knee ability has been buffed slightly, now dealing 3-5 damage. Metion Destroyer Gauntlet now deals 18-23 damage instead of a flat 20. Metion Rocket Barrage's environmental damage has been cut in half.

- The Metion Shotgun (still an assault rifle category weapon by the way) has had its base damage bumped up from a flat 4 to 5-7. Crit damage has been reduced to 4 from 5, and its magazine size has been bumped up by 1, giving it 6 shots per magazine. It now deals only 2 environmental damage. Its Metion Autofire ability now ends the turn. It no longer gains a +5 Aim boost, and it now uses an SMG range table. Does not have any weapon upgrade slots.

- The Control Grenade now does 4-8 damage (up from a flat 4), and does 5 environmental damage, up from 0.

- The Destroyer Cannon's damage has been buffed from a flat 15 to 18-23 to match the Metion Battlesuit's version. It also can be used twice per mission instead of just once.

- The Hyperdrive Serum Injector Vest now grants the Impulse ability (F_Momentum from Favid's Extended Perk Pack), which grants the soldier +10 Aim and +10 Crit Chance when attacking after moving with anything that uses a standard Aim roll (primary and secondary firearms, pistols, melee, the Skirmisher's Justice ability, etc.) in addition to its original effects. However, it cannot be equipped by Playable Aliens, SPARKs, or MEC Troopers due in part to missing animations.

- Flechette Guns cannot be equipped by Playable Aliens, SPARKs, or MEC Troopers due in part to missing animations.


- Custodian A.P. Rounds is a new ammo type that grants 5 Armor Pierce, just like the base game A.P. Rounds did.

- The Overseer Pistol is a new pistol based on the Exalted Custodian's. It does equal damage to a Beam Pistol, but with no Rupture and slightly better Crit Damage, and has a superior range table offering improved accuracy up close and at range. Additionally, it includes the Liquidator ability (Shadow Ops Perk Pack), allowing killshots made by this pistol to not cost actions.

- The Permafrost Rifle is a new assault rifle based on the Exalted Custodian Grandmaster's. It does equal damage to a Plasma Rifle, but with no Rupture, and has the same range table as well. It also has double the magazine size of a Plasma Rifle. It includes the Shiver and Running On Empty abilities, but does not have any weapon attachment slots.


- The ADVENT Exalted Custodian Powered Armor research requires the Battlesuits, Advanced Grenades, and Gauss Weapons researches to be completed. You can then start the research for 190 Supplies, 35 Alien Alloys, 10 Elerium Dust, 3 Elerium Cores, and 1 Exalted Custodian Corpse. You'll also need 8 Engineers and 8 Scientists. You get one Metion Battlesuit when the research is done. Additional Metion Battlesuits can be made in Engineering for 170 Supplies, 30 Alien Alloys, 20 Elerium Dust, 2 Elerium Cores and 1 Exalted Custodian Corpse each.

- The Metion Auto Shotgun no longer has its own separate research, and requires the Custodian Autopsy and Gauss Weapons research to unlock. They can then be built in Engineering for 50 Supplies, 5 Alien Alloys, 4 Elerium Dust, and 1 Custodian Corpse each. You'll also need 5 Engineers.

- The Hyperdrive Serum Injector Vest is now unlocked by the Hyperdrive Serum Injector Vest project in the Proving Grounds, which needs the Hybrid Materials research and the Custodian Mk2 Autopsy to be unlocked. The project costs 25 Supplies, 3 Alien Alloys, 1 Elerium Core and 1 Custodian Mk2 Corpse. You'll also need 6 Engineers and 6 Scientists. You get one Hyperdrive Serum Injector Vest once the project is done. More can be made in Engineering after, for 20 Supplies, 2 Alien Alloys, 3 Elerium Dust, and 1 Custodian Mk2 Corpse.

- The Destroyer Cannon is now unlocked by the Destroyer Cannon project in the Proving Grounds, which requires the Custodian Master Autopsy and the Battle Armor research to unlock. You'll need 60 Supplies, 6 Alien Alloys, 6 Elerium Dust, 1 Elerium Core, and one Custodian Master Corpse to start the project, as well as 6 Engineers and 6 Scientists. You get one Destroyer Cannon when the project is done. Additional Destroyer Cannons can be built in Engineering for 50 Supplies, 8 Alien Alloys, 5 Elerium Dust, 1 Elerium Core and 1 Custodian Master Corpse.

- The new Custodian A.P. Rounds are unlocked through the Custodian A.P. Rounds project in the Proving Grounds, which requires Hybrid Materials, the Custodian Master Autopsy, and Elerium research to unlock. It costs 40 Supplies, 4 Alien Alloys, 1 Elerium Core, and 1 Custodian Master Corpse to start the project, in addition to 6 Engineers and 6 Scientists. You get one Custodian A.P.

- The Metion Battlesuit, Metion Auto Shotgun and Overseer Pistol all have their own infiltration values, taking longer than equipment of equivalent categories due to their larger size (the Metion Battlesuit in particular takes as long to infiltrate as a SPARK does).

- Lots of Localization changes in order to make the function of certain items or abilities more transparent to the player, and to fix some grammar and punctuation errors.
