Metro Last Light DLC: Faction Pack out now

First of four planned add-ons hits Xbox Live and Steam

Deep Silver has released the first Metro: Last Light DLC in the form of the Faction Pack.

Offering three original campaign missions in which players are cast as specialists from the warring Factions, the DLC revisits some of the locations previously seen in Metro 2033. It will also feature new weapons and "the return of a truly terrifying mutant foe".

Priced at 400 MSP/$4.99/£3.99/€4.99, the add-on is available to download now on Xbox 360 and Steam. It will arrive on PS3 later today in the US and tomorrow in Europe.

The Faction Pack is the first of four planned Metro Last Light DLC packs, which can be pre-purchased at a discounted rate as part of the Metro: Last Light season pass.

Worldwide Metro Last Light sales across all formats matched the total achieved by Metro 2033 in its opening three months, according to Deep Silver.

In our Metro: Last Light review we said 4A's sequel is "gruelling, but worth the effort" and "a refreshing change from more traditional first-person shooters".
