The fixed version of my Alamo artillery missile system. Added lots of damage and made it splash over a wider area (if a single 0.2 ton Arrow IV missile already does a lot of damage, I don't see any reason why a 2 ton missile should not have the same damage potential, especially with it's shorter range). Thank you  prdarkfox for the comments, you helped me a lot with your advice on the rules. ^^
The alamo missile can be considered a WMD weapon. It carries a large warhead loaded with heavy bomblets, each one with the yield of a high-explosive AC/10 round. Beware Clanners: better have a look at the sky if you see a few black dots on the ground - it may be the shadows of a bomblet cluster heading your way.

Game Rules:
Weight: 5 tons
Critical slots required: 3
Range: 20/30/40, minimum range 10
Ammunition capacity: One-Shot weapon

The Alamo launcher may only be mounted on the left or right torso of a BattleMech (which may not have mounted jump jets in that location), or the front or rear side of a conventional vehicle. A unit that wants to fire the Alamo may not have spent any MP during the movement phase.
Alamo missiles are fired at a target hex instead of a specific unit. If the attack misses, the missile scatters according to the artillery rules.
The Alamo missile does 20 damage to all units in the impact hex and 10 damage to all unit in the adjacent hexes.
