From Halopedia, the Halo wiki
In Halo Wars Alice-130 is exclusive to the campaign and always has an AIE-486H machine gun. Like the other Spartans of Red Team she can be revived if killed.
Halo Wars 2
In campaign Alice-130 acts the same as she did in Halo Wars, barring Spartan slam. In Multiplayer Alice-130 is exclusive to Isabel and can be built at the UNSC Armory. Unupgraded Alice starts off dual wielding M6C magnums and is great against infantry, but only okay against vehicles, aircraft, and structures. Once upgraded with an M247H Alice will be effective against vehicles and aircraft. In Blitz Alice-130 costs 240 energy and features the Reflect ability that reflects half the damage Alice takes back to enemy units.
