Female marines will feature in Aliens: Colonial Marines’ co-op and multiplayer modes, Gearbox has announced.

The plan was always to include playable female characters, claimed Gearbox head honcho Randy Pitchford, and this announcement was early because of Internet pressure.

In July, an online petition spang up demanding the inclusion of female characters in the game’s multiplayer.

Six of the cast from the movie Aliens put their support behind the petition, and a total of 3881 signed overall.

In a post-E3 interview, Colonial Marines senior producer Brian Burleson said there were no playable female characters in the game.

Apparently he meant that there were no playable characters in the E3 demo, said Pitchford.

Aliens: Colonial Marines is due out on February 12, 2013.
