After being delayed to this month, the first micro-expansion for space strategy title Sins of a Solar Empire has finally launched.

Selling for $10 on Stardock’s Impulse service, the expansion adds new starbases, mine fields and other upgrades to the spaceship fleets. Dubbed “Entrenchment”, it marks the first of three planned micro-expansions to the game, all set to be released over the next year.

Stardock has already announced the next expansion, which will focus primarily on enhancing the diplomacy features of the game.

In more delay news, VE3D carries confirmation that Entrenchment, the upcoming microexpansion for Sins of a Solar Empire, has been delayed to January 2009.

While the retail release may have been delayed, those who pre-ordered the game will get to take part in a beta test to help balance the expansion. However, no date for the pre-order beta has been given.

Entrenchment is the first in a series of microexpansions for the game that will add new ships, technologies and more to the core title.
