- The Artillery Faction
- Special Ability: Creeping Barrage; align far edge of targeting zone with enemy trench, fire, and then tell your troops to charge. Rows of small shells will land in front of your troops and screen their approach. Time it right and you'll devastate your enemy just before your troops arrive. Time it wrong, and you'll troops will either be exposed or, worse yet, fall under friendly fire!
- All artillery abilities cost fewer stars to use.
- The Infantry Faction
- Special Unit: Stormtrooper: armed with a submachine gun and grenades (without having to research them first), this unique unit can fire on the run as it approaches an enemy trench.
- Unlocking Infantry Units costs 1 less medal.
