Hey guys. I'm new. Well this account is but I've been playing and strategizing here for years. So, I've got a pretty decent strategy for City Siege.
When you have enough money, get a cheap helicopter and use it to quickly evacuate the VIPs. You don't even have to shoot anyone because that chopper is FAST. Once you do that you can use the chopper the chop down some baddies on the roofs. Depending on the situation, usually you evacuate citizens at the same time you eliminate their nearest threat. But you can go through with a chopper, tank, or commando and evacuate them all before annihilating the baddies. If you choose to do that you can blow the baddies up with some artillery, tanks, or heavy choppers. This can be done on the last level as well.
Theres no need to promote your different soldiers for the most part, because it only boosts max hp. But you should if the unit is going to take a lot of damage like a tank that you may send through enemy lines.
I hope you appreciate this advice. Just remember, this isn't so hard of a game, you can beat it with all infantry. The heavier units are used mostly for speed.
Well , interesting stradegy , But how does one get enough money to get the helecopter. Or why not just get a heavy tank and go all scarface on them baddies!?!?
Well I recommend using a tank AFTER evacuating the VIPs and citizens. Otherwise you might accidentally kill them! As for the helicopter, just save up money until you get $25,000. What I did was beat several levels with simple units and eventually bought the helicopter and went back and perfected those levels so I got three medals.
Buy it Monster Sprites and then move by W,A,S,D or Arrows key and i finished the game 1 yeah ago and 5 months ago i get all the soldiers and if u don't have a enough money to buy them go to Google and type : ( City Siege hacked ) and u will have a lot of money to buy them
