IT'S brutal, bloody and very addictive.
Gears of War 4, the latest in the $1 billion franchise played by 45 million, features the most intense HD battle scenes of man vs monster.
Superb movie-quality scenery, a quick-moving plot and eerie music keep you moving from level to level, despite your apprehension about what might emerge from around the corner.
"We're going back to something personal, intimate, dark, and mysterious, being afraid of the boogeyman," its co-creator Rod Fergusson told IGN.
Set in the wilds of Sera, some 25 years after the time of Gears of 3, the game returns to the dark tones of the original.
Fighting as JD Fenix, the son of legendary hero Marcus Fenix, you face a desperate mission to save loved ones, joining forces with friends Kait and Del, and encountering everything from mega machines to ferocious windflares and lightning storms.
The opening scenes, especially without the gore and language filter on, show why this is not a game for the faint of heart - or younger teens.
Even for an adult, it's nightmarish with monsters emerging from all sorts of places, including embryonic-like fluid.
The game is massive - not just in the 60 gigabytes of downloads to set up - but in game play options.
As well as single campaign mode, you can rev up your Lancer with you friends and fight your way through the battles together over Xbox Live or a local split screen co-op, playing as either JD, Kait or Del.
Cross Play lets Xbox One and Windows 10 gamers play together in cooperative modes like Campaign, Horde and Co-Op Versus.
Gears of War 4 includes a new arsenal of weapons and combat tactics, while the wind storms bend your shots, making your battlefield tactics all the more vital.
Some of the new moves are ruthlessly savage.
As well as yank and vault kick, there's a bloody new combat-knife execution which is not for the squeamish.
New weapons include Buzzkill and Dropshot, to shoot around and over cover, bringing destruction from all angles.
The multiplayer experience is run on 60 FPS dedicated servers with new game modes including Dodgeball, Arms Race and super competitive "Gears" multiplayer mode, Escalation.
A new visible ranking system that drives online matchmaking and lets you stand out for your particular abilities.
In the next generation of Horde, you can team up with up to four other players, you can build and deploy defensive weapons and fortifications.
Having not waged war for a while on these types of games, I was pleasantly surprised about how easy it was to pick up with good hints along the way.
Published by Microsoft Game Studios and are developed by The Coalition, Gears of War 4 officially goes on sale on October 11, though its available from October 7 for ultimate edition owners.
