Conflict Zone - Attack faster

Attack faster:
Build structures that make units Barracks, V. Factories, etc., then have each of them to make units. For example, if you made two Barracks and told one to make fifteen soldiers and the other to make fifteen soldiers, both barracks will make them. This works for both IPC and GHOST. This trick will allow you to make soldiers and attack a lot faster.

Skirmish mode:
The best map is Sardines as you can build more on there. A good trick is to build all the newest things that comes out. However this will require a lot of money, and some of the new things you unlock are useless. For example, the planes, spies, commandos, subs, boats, advanced things, doctors, civilian helicopters, and grenadiers
