I've been playing around with some stats for the use of Battletech Mechs with Ambush Alley Games' "Tomorrow's War". These are not finished yet. Some stats are likely to change and will probably need some more balancing. I used the information of the Technical Readouts that I have to see what weight class the Mechs have, what equipment and sensors they carry and then tried to convert this into TW game mechanics.
For those of you who know TW, you might note that I have tried to "group" weapons when they are likely to be fired onto one target at the same time. I also came up with some ideas that are not included in TW (like using the LRM from Battletech as some sort of light artillery for Tomorrow's War, allowing to utilize them as indirect firing support for the grunts.)
I have split weapons into "main guns" and "secondary weapons" to restrict the Mechs in the way of how many can be fired during one activation. It also allows the player to choose from a list of weapons or to fire some in combinations, without overpowering these units. Armor values are taken by converting weight class (Battletech) into armor class (TW).
Where Mechs are weak in armor etc. I have tried to compensate by using "Common Vehicle Attributes" from TW, like "poor and absolete armor" to rate down the armor value for example. Or to increase capabilities the same way by using other rules.
These are first mock-ups. Just to show you where I am trying to go.
