Twelve years on and Metal Slug 3 still has some of the finest dot-pixel art and shoot-continuously-at-the-stream-of-enemies gameplay we've ever seen. Now it's finally coming to Steam. Par usual with Steam launches, Metal Slug 3 is available at a discount for pre-purchasers. From now until February 7, it'll be 25% off, taking it from $7.99 down to $5.99. Time to get back in the saddle – or back in the Metal Slug tank, as it were.
