Store Adjustments
- Apache released for MC
- Spectre released for MC
- Multiple warhorns released for MC
Note: We’ve kind of been slacking on updating the warhorns released for MC. We are doing a large backlog of old warhorns and adding them all to the store for 750 MC. In the future, a mech pack, booster, or legend will have its warhorn released for 750 MC 8 months after the pack releases. Loyalty, reward, or prestige warhorns will not be released. Standing and hanging items from these packs will not be released. The warhorns that have been added to the ingame store for 750 MC this patch are Clan Gatlin, Retro Mini, Retro Handheld, Cicada, American Thanksgiving, Stryker, Warden, Hunter, Predator, Bloodname, Crusader, Hatchetman, Moonwalker, Juggernaut, Dreadnaught, Scattershot, Arges, Seraph, Desperada, Howl, Gausszilla, Stone Crusher, Stone Rhino, Scaleshot, War Emu, Warlord, Hashke, Abaddon, Blight, Gorewing, Onyx, Longbow, Aksum, Spitfire, Sovereign, Li Dok To, Red Reaper, Kasai, Black Hawk-KU, Bullshark, Ferroblast, Behemoth, and Argent.
Gameplay Changes
- Wolf Dragoons Booster Pack badge changed to Wolf Dragoons logo. The decal and cockpit item art have not changed.
- Conquest returned to 750 tickets to win and reactivated for Quick Play.
Note from Tiyos: “While I feel the Grand Conquest event was a successful experiment, there’s a lot I learned on how it can be improved for the future. The biggest need is adding Faction Play style spawn walls and perhaps even turrets to prevent spawn camping in such extended matches. I hope to bring back Grand Conquest again but at some point down the road where I have more time to properly plan things and make the required changes.”
- When mechs look down far enough for the arm reticle to clip through the minimap, the minimap now becomes semi-transparent to allow the player to see the arm reticle and other HUD elements under the minimap, as shown in the example below. The minimap behaves as before in any other situation.
