Ran the Alpha Strike numbers on the TMP-4M, the results are... interesting.
You wind up with the same armor/structure (sensible, if odd given the armor rearrangement on the TMP-4M is easily the best thing about it; the arms can now take twin PPC hits without a potential crit on the Gauss)... but the damage changes.
You get Short 4, Medium 4, Long 2, with Overheat 1.
TMM 1 on movement 8"/10"j.
I think the result would be a lower-PV alternative to the TMP-3M. Lower base damage, but you pay less for it and make up the difference via overheating.
I admit I was surprised, but mostly in a good way. The TMP-4M is a clear upgrade in the classic boardgame (I'd actually call it "pretty damn good"), and a 'downgrade' (but with a PV reduction to account for this) in Alpha Strike. My sole complaint is I feel the Snub Nose PPC conversion rules for Alpha Strike are nonsensical.
So I ran the BLR-6M/6C too. Got something like...
TMM 1
Armor 8, Structure 7
Short 4, Medium 5, Long 3
Overheat 0 (or possibly 1, this is a borderline case)
Abilities: CASE plus whatever Command Console gives us.
This is pretty neat. It's comparable to the Grand Titan N11M, doing less damage at most brackets but being slightly more durable and having command abilities. Clearly a useful addition in both versions of the game.
