Frre units
== Under the "Free Units" tab, you can obtain some free elite units by inviting your friends to play. If your invited friend plays, that counts as one referral.

It may take many referrals to get top elite units, but it saves gold for those who cannot purchase elite units.

List of Obtainable Units and CostEdit

Special Forces - 2 Allies

Elite Tank - 5 Allies

Elite Rocket Battery- 10 Allies

Elite Eliminator - 10 neighbors
