So whichever team rolls out a longtom first, wins?
The mappers could put up base AMS around the objectives to take down the LT shells, LRMs, and Arrows (not sure if it works on Fbombs). Course that would probably make Gauss, ER LBL/PPC the weapons of choice.
This is similar to how it was implemented. The objectives were inside a walled base with huge indestructible walls several times taller than any mech. The walled bases had a set of doors on one side that were
destructible and had massive amounts of HP. The objective itself also had massive HP. It really took several mechs firing on it constantly for almost a minute to bring it down.
When the doors were under attack, there was even a warning to the team stating so, and when the doors were destroyed another warning came. A Long Tom would run out of ammo before destroying the objective if it didn't have an APC nearby.
All in all it was a lot of fun, and I wish it would have made it into the game proper.
This mode was created through the efforts of ONE MAN (<3 Frost). I'd love to see it implemented now if only to rub it in the noses in some other game devs who can't seem to get a handle on what proper innovative game modes look like. Sorry, I couldn't help it.
