Bullshark Void Killer and War Ghoul
Our legends this month are the Bullshark War Ghoul and Clan Bullshark Void Killer, debuting a new special weapon!
The Railgun will be a locked weapon unique to the two Bullsharks carrying it in their artillery mounts, they won't be added to the general loot pool. These two legends will release in a single pack with a single battlepass, like the Hashké and Abaddon. While each side torso has 5 slots taken for the Railgun mount, losing an ST will not crit out the Railgun. This means you can run a standard engine build if you desire. Both clan and IS railguns will have the same stats:
- Weight: 30 tons
- Damage: 40 pinpoint + 12 splash on each side
- Ghost Heat Limit: 1 (adding any PPC will incur heat penalty)
- Heat: 20
- Cooldown: 7.5
- Velocity: 2000
- Range: 810m/2050m
- Ammo per ton: 4(6 with skills)
- Weapon Health: 15 (it can only be crit out in the CT)
- Explosion Chance: 90%
- Explosion Damage: 35 (damage only applied to CT)
- This weapon uses the same charge and screen shake behavior as Heavy Gauss




The War Ghoul and Void Killer Legendary Pack
will be Available for purchase on the MWO Store and Steam
Store Adjustments:
- Dragoon Booster Pack mechs released for C-Bills
- Fire Moth released for MC
- Bane Warhorn released for MC
Weapon Changes:
- Added railgun ammo skills to IS and Clan skill tree ammo nodes
- Increased LRM10 minimum heat penalty threshold to 5 (from 4) - You can now fire four LRM10s with no heat penalty
- Increased Clan LRM 10 minimum heat penalty threshold to 5 (from 4) - You can now fire four cLRM10s with no heat penalty
- Clan LRMs now fire missiles in pairs. This effectively cuts their duration in half.
Omnipod Changes:
- Added Gargoyle GAR-P right torso omnipod for C-Bills. This omnipod will contain 2 iJJ
- Reduced iJJ count in GAR-M Left Torso to 2 (from 4)
Note: The GAR-M having 4 iJJ restricts its build variety a little heavier than we hoped. By reducing the count to 2 in the GAR-M LT, players will gain 4 extra tons to spend. Players who want to keep their 4 iJJ builds to jump to the moon will still be able to by equipping the newly released GAR-P Right Torso. This preserves the jump capacity while adding more flexibility on the mech.
Bolt-On Changes:
- Non legendary/booster mech variants can now equip legendary/booster bolt ons(this may not be available for all variants of a chassis, as sometimes specific variant geometry or hardpoints will block these bolt ons). These bolt ons are still locked to legendary mech purchasing only, but players will now have more freedom in choosing where these bolt ons go.
