War Commander puts on periodic Special Events, currently at about one per month. During these Events the player receives Event Experience Points (eXP) which should not be confused with the separate standard Experience Points (XP) used to raise players in Rank & Levels. The eXP can be used to Unlock and obtain Special Event Units aka "Prizes" which consist of special Units, Buildingsand Schematics that would otherwise not be available.
Information Given in Event Shop :
Which Prizes are Available or Locked.
the Requirements and Cost of each Prize.
A graphical running total of eXP still needed to obtain each Prize
And when a Prize is Individually selected inside of the Event Shop a Description of that Prizes and the exact amount of remaining eXP needed to obtain it is given.
How The Event Shop Works :
The Shop is only accessible during and for a shot period after each Special Event. The player may use their eXP at any time during and for 48 hours after the Event, know as the "Use It Or Lose It" period.
The Event Shop is accessed thru the Special Event Panel. Press the "Prizes" button to open the Event Shop.
Several new Prizes are added to the Shop each Special Event. These are usually but not always related to the theme or story of the Event.
All past Prizes are available in the Shop. The exception to this are newly released Prizes. At the conclusion of an Event the new Prizes become unavailable or "Locked" for 1 to 2 Events as follows :
1 Event Lock = Standard & Elite Units, Buildings & Turrets and Schematics & Components.
2 Event Lock = Unique Units.
The eXP is only valid for use during the Event in which it was earned. The eXP does not carry over from Event to Event, hence the "Use It or Lose" name for the period after an Event.
Some Prizes have Requirements before they can be Unlocked. Some require the player to have aTech Center of a certain level. Others require that a certain other common Unit be Unlocked first. And finally the Elite versions require that Non-Elite version, whether it's a common Unit or another Prize, also be unlocked prior to being able to obtain them.
Advance Missions Prizes are not offered in the Event Shop.Advanced Missions award Special Units also but since these are not "Purchased" with eXP they are not available in the Event Shop. These Units are the Colossus, Havoc, Behemoth and Vanguard.
