You can now buy upgrades in Battlefield 4. If you're jumping back into the game to try out the CTE or see how it's working, you can skip leveling up by purchasing battlepacks directly.

A post today on the Battlefield blog announced that battlepacks would be available for purchase, $1 for bronze, $2 for silver, $3 for gold. The packs contain all the same things you'd get in a regular battlepack via leveling up: XP boosts, dog tags, weapon attachments, camo patterns, etc.
