This is a variant of the Marauder for Battletech. It swaps speed & internal armor for missiles.
The original mech record sheet was assembled by KHYRON42, & the original image was made by Anthony Scroggins. (at least that’s what the original record sheet said.) (With help from CATALYST, also)
The missile launcher doesn’t look quite as good as the original’s weapon, but I think it still looks OK. (I added SPIKES)
