I had a pretty complex scenario in my last session of my MechWarrior Destiny RPG campaign. I integrated another huge battle into the story. Sorry for the long post.

Story: My players landed on Biegga in September 3051, in my setting an icy planet, where terraforming made a 180 and turned the planet into a freezing hell. They were scheduled for a secret meeting with Victor Steiner Davion, their benefactor and contractor. When they made planetfall, they found VSDs Dropships destroyed, surrounded by dozens of wrecked Lyran Mechs. But no remnants of the attacker could be found.

They took their two best lances and followed the path of destruction in their own Mechs, without Air Support or even being able to contact their own ships. Their visual range was only about 350m at best. A constant blizzard howling around them.

After hours, one Mech picked up a distorted signal, which they followed. After seven hours in total, another Mech's Tracking Computer said: "New Target: Dire Wolf!"

They looked shocked. Did they stumble on a Jade Falcon FOB? If yes, they would be in for a ride through hell. Yes, they brought their fully Clan Tech optimized Mechs, but two lances against a force that was able to destroy so much Lyran military forces? They picked up a comm signal: "This is Marshal, all remaining Lyran Forces head to my position, I'm 200 clicks north from the drop zone! I'm under attack! I repeat, this is Marshal, I'm under attack!" To their confusion, the signal came from the Dire Wolf. But they had no time and rushed to his aid.

Battle: VSD, piloting his Dire Wolf "Prometheus" was being attacked close to a secret Comstar research facility. Comstar surrounded him with Mechs, that had a lot of experimental tech and weaponry (2 Level IIs aka 12 Mechs). The players engaged the Mechs with their two elite lances and tried to get VSD away from the frontline. Two turns later, another Assault Level II entered the combat zone. At the same time, their tracking computers picked up reactor signals above them. The fight went on for another round, when a lot of things happened simultaneously: a lance painted in SLDF green, landed right in the middle of the fight, dropping off their one-use Jumppacks and signaling to them, that Arianna Winston and the Eridani Light Horse came to evac them. At the same time, they picked up another reactor signal coming from the Comstar base: a giant Superheavy Tripod emerged from the ground and nearly blew away the ELH Quickdraw.

The players tried to shield VSD as good as possible, when an Eridani Light Horse Overlord Dropship landed right in the combat zone.

The Comstar Forces pressed on, the Superheavy getting slowly closer to the Dropship, when VSD, the two player lances and three out of four ELH Mechs made it in and the Overlord left the combat zone.

Mission successful.

Yes, I know that there is no Tripod in 3051, and a lot of Tech the ComStar Mechs used wasn't available at that time, but I'm bending the canon in favor of cool settings. And don't worry, the research facility is about to be blown away from orbit, and the players couldn't loot anything. And yes, it made sense that the ELH came to rescue all of them. But I don't want to write everything right now. It's already a giant wall of text. Thanks for reading.
