Each player controls a small squad (5-10 units) and another player controls all titans. All rolls would be made with a D12 (except maybe, for the damage calculation against titans)

The stats are the following:

Health: (Health stat ÷2) number of times a character can be hit before dying, if 1/3 is lost, the character is wounded

Leadership: Rolled when another unit fails a "Calm" check. Can un-stun the characer with a speech

Air-speed: (Airsped stat ÷2 +3DMG speed stat) number of tiles a character can move per turn. Also determines air-dodge

Ground-speed: (Ground-speed stat ÷2) number of tiles a character can move while running per turn. Also determines ground-dodge

Riding-speed: (Riding-speed stat ÷2 +Horse) number f tiles a character can move while mounted in a horse. Also determines riding-dodge stat

Maneuveur: Roll every-time the unit is doing something "complicated" with the 3DMG (I still need to specify this part), or attacking while air-bound

Aim: Shooting a hook at a small area (nape, ankle, person, etc)

Blade-usage: Roll against this stat after an unit uses their sword. If the rolled number is higher than this stat, one blade breaks (some 3DMG have more slots for blades, some less)

Gas-usage: (I still need to think about this one)

Calm: (Calm stat -number of deaths witnessed that day)Avoid getting stunned after seeing another unit die.

Will: (Will stat ÷2) if wounded, roll against this stat once per turn to take an action. Can also be used to shape-shift into a titan (in this case, remove the ÷2)

Awareness: Roll against this stat to notice a threat. (sight range is Awareness stat *3)

Special stat: Varied
