Boosters

Boosters
There are different booster options available depending on the level you're playing. You will be given an option of three boosters per level and each will cost either 10 or 20 crystals. You will recieve one booster per day for free and can choose which booster you want between the three options for each level. You may also choose to not use your free booster if you want to save if for a later level. The free boosters do not roll over from one day to the next, so there is no benefit to saving it for the following day.

Free Tank
Depending on the level you will receive a free light, medium or heavy tank. It will show a picture of the type of tank you will receive.

War Funds
You recieve 20,000 war funds. If this is an option, there will always be at least one factory or airport on the map. This option is one of the best because as long as you have control of an airport or factory, you can produce a lot of units with this amount.

Move 2x First Turn
Your units can move twice as far as they normally can for your first turn. You do not recieve two first turns.

Critical Attack
You receive +50% critical attack
