Battalion Commander

Get armed to the teeth and fight your way through the enemy territory packed with soldiers, tanks, watch towers and helicopters. You’ll need help from your fellow soldiers trapped by the foe, tons of weapons and upgrades and mighty skills to survive and accomplish your mission.
And your mission is to destroy the secret enemy base that you will find in the end of your journey. If you manage to stay alive of course!
You start the mission alone, but you will find cages with trapped allied troops that will join your squad once you set them free. On top of that you have a mighty skill that slowly charges as you go and can eliminate all the enemies around you in a single strike!
With each mission you gain experience and get higher ranks to have a bigger squad and unlock more upgrades, buy new weapons and skills.
No one said it's going to be easy, but if you failed the mission, you can regroup and buy valuable upgrades and weapons, unlock new allied troops and skills.
