All done . Pretty easy game if you know the level and the layout of civilians and VIPs. Too shame that the game basically doesn´t push you to make your army strategy. I finish all levels just with 2 soldiers (Commander and the Jetpack man).
P.S. about the "burning skies" quest. I shot the gas canister and it just flew to the sky and miss the helicopter and it still triggered the quest.
@lywzc Try to achieve the combo in different level. I had no problems with quests.
Got me a glitch during "Boom Town" as well... I saved all the civilians and VIP's, got all the stars, but when I was on my way to kill the remaining baddies, the screen broke up! The floor was missing on several places and I couldn't shoot anymore, only walk around.... had to refresh the page to get back into the game.
That glitch sounds exactly what I was experiencing. It almost seems as though explosive weapons set it off (such as the Rocket Helicopter), but I'm not sure.
Ah, well. I finished the badges so I'm not worried about it anymore. The world revolves around me.
Nice easy and fun game. My soldiers of choice doing the quests:
Spy
Jetpack
Molotov
Heli-T
Heli-R
Some words on the quests: Second Life
Simply let one of your units die and resurrect them by clicking on the "Fallen Heros" Button in the main menu.
Arsonist
Can be done in nearly every stage near the end. Simply set everything on fire using the Molotov class.
Expendables
Buy every class slot. You do not need to level up every class to general! Simply buy a lot of Rifle classes (they are the cheapest ones).
Hot Pot
This should come automatically in your playthrough. Simply drop an enemy into lava by e.g. destroying the bride.
Sharp Shooter
Easiest done in "Baddy Bunker 2". Shoot the fireworks box in the middle of the map with the Rifle class and watch the fire.
Infiltration
Self-explaining. Work your way through "Baddy Bunker 2" using only the Spy.
All gold
Getting gold medals in this game isn't hard at all. Get all the stars, rescue all civilians and don't get killed. I found a pretty decent strategy is using the Spy first to rescue all civilians and getting most of the stars. After that go nuts with some explosive classes because you don't have to consider about the civilians anymore.
Burning Skies
Hit a gas canister by gun class when a helicopter is above. The canister will fly up and hit the helicopter.
There is a chance the map won't load.
At some point I had all except the last two quests and they all disappeared.
Checked in the profile they were earned but they are not showing below the game - had to redo.
