First, Metal Gear Solid V: Ground Zeroes, the prologue to Metal Gear Solid V: The Phantom Pain which launches in September, comes to Xbox One – followed by the open-world, tongue-in-cheek survival title How to Survive: Storm Warning Edition.

On Xbox 360, fans get treated to two of the best first-person survival-horror shooters ever with Metro 2033 and its sequel Metro: Last Light.

As usual, all games are available only for a limited time, as part of the ongoing Games with Gold program.

Metal Gear Solid V: Ground Zeroes ($19.99 ERP) Available from August 1-31 on Xbox One

Just when you couldn’t wait a day longer for your Metal Gear fix, Games with Gold comes through with a chance to play Metal Gear Solid V: Ground Zeroes completely free on your Xbox One. If you haven’t had a chance yet, this latest chapter in the outstanding Metal Gear Solid stealth-action series is set in 1975 during the Cold War era. The player takes on the role of Big Boss, as he infiltrates a U.S. military black site in Cuba to rescue a couple of high-value allies who are being held captive. Players will use gadgetry, stealth, and plenty of quick thumbs (and quicker thinking) to overcome the game’s challenges. They’ll also find that Ground Zeroes is far less linear than previous Metal Gear Solid titles, with a more open-world feel – and many different means by which to accomplish objectives.

How to Survive: Storm Warning Edition ($19.99 ERP) Available from August 16-September 15 on Xbox One

Of course, government conspiracies and deep-dives into secret societies running the new world order might not be your thing every night. Sometimes, you just want to bash some zombie heads with a weapon that you’ve fashioned from disused airplane parts. That’s where How to Survive: Storm Warning Edition comes in. Playable solo or with a buddy, How to Survive drops you onto an island with nothing but your wits and some basic tools, and challenges you to survive the elements and some ravenous zombies. Fortunately, stashed around the place are titular guide books that provide information on the game’s in-depth crafting system, action-packed combat, and tongue-in-cheek sensibility. This one is all about pure enjoyment, so don’t spend too much time worrying about weapon optimization or getting your combos just right; get in there and have some fun.

Metro 2033 ($19.99 ERP) Available from August 1-15 on Xbox 360

Now, if you’re a Games with Gold member and an Xbox 360 gamer, boy did you luck out in August. The Metro series of post-apocalyptic first-person shooters is multi-award-winning for a reason. Both titles, Metro 2033 and Metro: Last Light, are set in the Moscow subway system in the decades following a nuclear holocaust. Surviving humans huddle in the subway depots and eke out a living tinkering with old technology, raising the few animals and plants that they can, and by scavenging in the unexplored tunnels – and, if they’re really daring, on the partially irradiated surface. Bullets function as currency for buying and selling stuff, and it’s also (obviously) ammunition for the game’s weapons. So players will need to be very careful about how much they spend – both in the hands of greedy merchants, and in the skulls of Metro’s many horribly mutated baddies.

So players will need to be very careful about how much they spend – both in the hands of greedy merchants, and in the skulls of Metro’s many horribly mutated baddies.

But, for the most part, players won’t need to shoot their way through obstacles; sneaking, tinkering, laying traps, and working with fellow humans are all viable ways through the Metro series’ many dangers. Of course, your human allies can just as quickly become enemies, as no one can be trusted in a world where life is cheap and survival is paramount. Did we mention that both games have fantastic, compelling storylines based on a series of acclaimed novels?
