Probably one of my favorite features of Mass Effect 2 is the Cerberus Network. If you don't know what that is, I'll explain. The Cerberus Network is given to you in the form of a code, when you buy Mass Effect 2 new. On top of getting all the latest news, you also get free downloads that would originally cost you money. Bioware has released a few DLC packs under the Cerberus Network; one including a small mission, and the other including a new character, achievements, and missions. Now a third pack is being released tomorrow February 9th, which will include a new armor and a new shotgun.
Now I really don't see this as a huge update but if it gives you free stuff just for buying the game, then it seems worth a download. These happen to be a Cerberus armor, and the Eviscerator Shotgun. The armor is going to increase your heavy weapon ammo, your health, and shields by 10%. The Shotgun is going to be able to pierce armor, and be effective at longer ranges as well as short range. This could be really useful; especially when you are fighting the boss of the level.
Make sure you pick up this free download February 9th, to try out all the latest and greatest from Bioware.
