List of Walkthrough Guide on Battalion Commander
Battalion Commander gets easier over time to win as you progress and unlock more upgrades. For me, I will equip myself with Shotgun and Napalm Wave. Simply reasoning, because spread bullets are more effective to kill, and Napalm Wave have a fairly short cooldown time. I win the game at after upgrading Nanobots according to my recommended build. A fast way to get quick cash and XP. Buy the Fast Start as soon as you can, when you start the mission, try it hit as many foot soldiers as you can. After your car explodes and you can collect all the dropped money and XP, quit the level and restart + repeat. Very fast way to get all the upgrade and ranks, however, it's a grind fest.
If you've noticed, I leave Minigun, Rocket Launcher, Heroic Dash and Fast Start at the very end of the build. Personally, I find Minigun and Rocket Launcher less useful than Shotgun. In my opinion, Heroic Dash is pretty terrible in practice... All the enemies can target, including behind them. While you and your allies are mostly just able to shoot straight ahead. "Heroic Dash" should be called as "Horrible Death." A fast start is quite useful but unable to toggle it off and may cause lag. I feel it's best to upgrade it last.
