I actually had one fairly recently. We had a three way free for all with 3 players controlling 3 mechs each. One heavy one medium and one light. We placed four map sheets together, the forested one, one of kat wylders maps, and two classic
'battletech maps" (the ones with the lake in the middle)
I rolled with a Grasshopper, Dervish, and Panther. Facing my friends K2 Catapult, Vindicator, and Spider & my Dads Warhammer, Vindicator, and Firestarter.
Anyways we all started in different corners. I moved my mechs together to the edge of a small grove of trees in the forested section of the map over two turns of positioning. My friend moved his Spider last, and jumped up on one of the hills into my line of sight. Exactly 21 hexes from my grasshopper. Declare firing for my LRM5, The only weapon in range this turn. Mods meant I needed a 12 to hit, rolls a 12, rolls for missiles hit, 11 (5 missiles hit) rolls location, 12. Head hit. Blew out some sensors but the Spider survives.
Positioning ensues and I get another 12 to hit on the Spider. I fire the LRM5 again and get the same sequence of rolls, decapping spidey.
The game goes on and my Panther gets caught out of position and get's wrecked contributing little. My Dervish goes down the next turn and while landing some good shots fails to put anyone down.
Over the next few turns my Grasshopper manages to systematically decapitate every mech on the field My friends K2,with a medium and then a large laser in the same turn, followed by my dads Vindicator with the Large critting the cockpit, then the Warhammer with a Large that crits the cockpit. Miraculously up until killing the Warhammer very little damage had been dealt to the Hopper, all in armor. The Warhammer got the Hoppers arm.
By this time both my dad and my friend have horrified expressions on their face as they both turn against the headcapping Grasshopper. I decide to split my fire and Fire my lasers at my friends Vindicator (which took an LRM5 head hit earlier from the Hopper.) and get a medium to connect. Boom cockpit. The LRMs manage to hit my dads remaining mech, the Firestarter and I get a 2 on the location table and then rack up 2 engine hits.
I get some pounding that turn and lose a few movement points. I lose initiative and the Firestarter runs behind me and tacs my gyro with a small laser. Mech down.
Somehow my Grasshopper managed to headcap 5 out of the 6 mechs opposing me, with no pilots managing to survive, and a badly beat to hell firestarter ends his reign of terror.
It was a fun game though!
