- The main Bitterfrost Protocol project in the Proving Grounds is now cheaper: it only costs 3 Alien Alloys, 5 Elerium Dust, and 1 Elerium Core. Remember: you will also need the Frost Bomb in HQ's inventory (NOT equipped on a soldier); the Proving Grounds will borrow it for this project, and return it when they've finished.

- Cryolators have been buffed in damage across the board. They still do less damage than Immolators, though. You still get one basic Cryolator after finishing Bitterfrost Protocol research.

- The Cryo Launcher and Superior Cryo Launcher have both had their radius increased by 1, and now hold two rockets each instead of just one.

- The Cryo Launcher is built one at a time in Engineering after doing the Cryo Launcher Project in the Proving Grounds. They cost 30 Supplies, 2 Alien Alloys, 3 Elerium Dust, 1 Elerium Core and 1 Advent Cryo Rocketeer Corpse each. The Superior version is built one at a time in Engineering after completing the Superior Cryo Launcher Project. They cost 50 Supplies, 5 Alien Alloys, 6 Elerium Dust, 1 Elerium Core, and 2 Advent Cryo Rocketeer Corpses each in Engineering after.

- The Cryo Launcher Project in the Proving Grounds is unlocked by the Advent Cryo Rocketeer Autopsy and the Battle Armor research. Starting it costs 30 Supplies, 4 Alien Alloys, 2 Elerium Dust, 1 Elerium Core, and 1 Advent Rocketeer Corpse. You also need 3 Engineers and 3 Scientists on staff. You get one Cryo Launcher when the project finishes.

- The Superior Cryo Launcher Project in the Proving Grounds is unlocked by the Cryo Launcher Project, the Plasma Grenade project and the Battlesuits research. Starting it costs 50 Supplies, 5 Alien Alloys, 6 Elerium Dust, 1 Elerium Core, and 1 Advent Rocketeer Corpse. You also need 6 Engineers and 6 Scientists on staff. You get one Superior Cryo Launcher when the project finishes.

- Bitterfrost Rounds are unlocked by the Bitterfrost Rounds Project in the Proving Grounds. They are built one at a time for 10 Supplies, 1 Elerium Dust, and 1 Advent Cryo Rocketeer Corpse each in Engineering after.

- The Bitterfrost Rounds Project in the Proving Grounds requires Hybrid Materials and the Advent Cryo Rocketeer Autopsy to unlock. Starting the project costs 20 Supplies, 1 Alien Alloy, 1 Elerium Dust, 1 Elerium Core, and 1 Advent Cryo Rocketeer Corpse. You also need 3 Engineers and 3 Scientists on staff. You get one Bitterfrost Rounds when the project completes.

- Frostweave's HP bonus has been buffed by 2.

- Frostweave is unlocked by the Frostweave Project in the Proving Grounds. To build one in Engineering after, you need 15 Supplies, 1 Alien Alloy, 2 Elerium Dust, and 1 Advent Cryo Priest Corpse.

- The Frostweave Project in the Proving Grounds requires Hybrid Materials and the Advent Cryo Priest Autopsy to unlock. Starting the project costs 25 Supplies, 4 Alien Alloys, 1 Elerium Core, and 1 Advent Cryo Priest Corpse. You'll also need 2 Engineers and 2 Scientists on staff. You get one Frostweave upon completion of the project.

- Bitterfrost Warhead and The Winter King's Fangs have been disabled, as have all of the Bitterfrost-related Proving Grounds projects other than the main Bitterfrost Protocol one (Cryo Launcher projects have been added back under a different template name so I could make them non-repeatable, since further launchers are built in Engineering). Bitterfrost Warhead will be re-added whenever I get around to adding Superior Explosives to Mod Jam's roster.

- The Cryolator's primary attack as well as its version of Chemical Storm have been added to the list of abilities that Quickburn can make a free action (any wiseass who thinks ice can't burn, go stick your hand in a bucket of dry ice and then get back to me).

- The Cryolator's overwatch is now affected by the Sentinel and Rapid Reaction abilities.

- Cryolators have infiltration values now. They're chunkier than Immolators and thus take a little longer to infiltrate.

- The Bitterfrost Blood Gene Mod has had its costs adjusted. Supply costs are reduced by a flat 10, and Elerium Dust costs are reduced to about one-tenth of what they were. Additionally, it no longer reduces Will be default. It now additionally requires 2 Cryolite.

- Some localizations are updated.
