An e-mail with a code said the code would give teleport charges, but those are no longer in the game. the code gave the paint, container, and the 1000 crystals.
"If you activate this code within a week, you will get:
* 100 Teleport charges - use them to get into ranked battles.
* 1000 Crystals - buy a turret or research a module.
* “Winter” paint - because you have to stay in trend.
* “Steel” container - that contains a stylish steel skin for your turret or hull."
