I don't do this very often.
I just downloaded the new MegaMek Dev so decided to put it through its paces with a Princess vs Princess battle. Having just had a frustrating defeat which saw my fast moving Ghost Bears crushed by slow moving, low BV forces I decided to send in a Ghost Bear 'Mech designed exactly for that. The Mastodon.
Mastodon Prime (Princess)
Mastodon Prime #2 (Princess)
Mastodon Prime #3 (Princess)
Mastodon A (Princess)
Mastodon A #2 (Princess)
Mastodon A #3 (Princess)
Mastodon B (Princess)
Mastodon C (Princess)
Mastodon D (Princess)
Mastodon D #2 (Princess)
The weight is carried by Primes and As. B and C are there for specialist effects. D is fire support.
Getting a bit over 40K of BV I auto rolled 40K of Inner Sphere 'Mechs spread over 20 units.
Hermes HER-4M (Princess1)
Wolverine WVR-10V2 (Princess1)
Catapult CPLT-K3 (Princess1)
Thunderbolt TDR-10S (Princess1)

The pilots were a bit inferior, but you can't complain about 11 assaults.
3 x 3 map. Combination of Battletech and Desert Hills 1&2 so no great stretches of clear LoS.
Both sides banged away at each other for about 20 turns. The Mastodons lost 5, 1 head hit, 2 ejections, 1 retreat and one hard death. 13 Inner Sphere 'Mechs remained.
Round 26. Another head hit, 10 vs 4.
Round 32. Gyro destroyed, eject, 7 vs 3.
Round 40. Gyro destroyed, eject, 2 vs 2.
By round 42 it was all over with two Mastodons remaining with 290 points of armor between them. MegaMek leaves burnt out corpses on the map. The trail of destruction was awesome to see. A carpet of black.
Given the armor difference I was downright shocked to Clan 'Mechs get the win.
I am attaching the entitystatus so you can see the details. Converted the gamelog to txt. Now it fits.
