About the game

This bundle includes Serious Sam 4, Serious Sam: Siberian Mayhem, and Serious Sam: Shatterverse.

Serious Sam 4

Serious Sam 4 reignites the classic FPS series in a high-powered prequel loaded with an explosive arsenal, intergalactic carnage, and perfectly timed one-liners.

Humanity is under siege as the full force of Mental’s hordes spread across the world, ravaging what remains of a broken and beaten civilization. The last remaining resistance to the invasion is the Earth Defence Force led by Sam “Serious” Stone and his heavily-armed squad of misfit commandos.

Croteam returns with a high-powered prequel to the Serious Sam series that scales up chaos to unprecedented levels. The classic Serious Sam formula is revamped by putting an unstoppable arsenal up against an unimaginable number of enemies that requires players to circle-strafe and backpedal-blast their way out of impossible situations.

Serious Sam: Siberian Mayhem

Serious Sam: Siberian Mayhem is a new stand-alone expansion to the world of the classic FPS series. Join the fight against Notorious Mental on a journey through the wild lands of Russia, and find your way through this lost chapter of Sam Stone's adventures.

Welcome back to the world of Serious Sam 4 in 'Siberian Mayhem' - a new standalone chapter in the adventures of 'Serious' Sam Stone. Make your way through the vast Russian landscapes on a quest to catch up with the traitorous General Brand, who remains one step ahead of Sam at every turn. The road is long, and there is oh so much to see.

Co-developed by Timelock Studio and Croteam, 'Serious Sam: Siberian Mayhem' presents an expanded look at a familiar journey full of forgotten stories, unexplored places, and Sam's trademark guns-blazing battles against Mental's Horde. Join the fight, comrade!

Serious Sam: Shatterverse

Serious Sam: Shatterverse is a co-op roguelite FPS for 1 - 5 players. Blast through shifting universes, stack wild boons, bend the rules with run modifiers, and hunt Mental's deadliest forces. Fall fast. Come back louder.

Serious Sam Stone is back, but this time he's not alone. Uber Mental's maniacal machinations have fractured the walls between universes, and now Sam's from multiple dimensions must learn to work together to repair the Shatterverse.

As part of the Serious Program, a multidimensional force opposing Uber Mental, you'll travel across shifting universes to finish battles other Sams couldn't. Mental has been hunting the hero across realities, and in many timelines, he's already won. Now, it's your turn to push back. To advance, you must bring down his five lieutenants, each a formidable boss in search of total annihilation.

Wield a relentlessly destructive arsenal of devastating weapons, unlock powerful boons, and experiment with run modifiers that reshape gameplay. In true roguelite fashion, death is never the end, and each run opens the door to new strategies and limitless possibilities across the Shatterverse.

How to activate

Guide for Xbox Series X|S

Primary — the game is shared with your own profile

1Press the Xbox button, open "Profile & system" → "Add or switch" → "Add new" and sign in with the login and password from your order.
2Now open "Settings" → "General" → "Personalization" → "My home Xbox" and choose "Make this my home Xbox". This is what shares our games with every profile on your console.
3Switch back to your own profile, open "My games & apps" → "Library" and install the game. The internet is only needed for the download.
4Launch the game from your own profile: achievements, saves and progress stay yours, and after the installation the game works offline.

Only one console at a time can be the home Xbox for our account — that is the slot you bought. Please do not change the password, the email or the two-factor settings of the account, or the access will be blocked.

Secondary — you play from our account

1Press the Xbox button, open "Profile & system" → "Add or switch" → "Add new" and sign in with the login and password from your order.
2Open "My games & apps" → "Library", switch to our profile in the top-left corner and install the game.
3Launch the game while our profile stays signed in, and keep the console online: the licence is checked over the internet.
4Use your own profile for everything else — the game stays available as long as our account is signed in on this console.

Secondary costs less, but it needs a permanent internet connection and our account stays signed in on your console.

Activation code

1On the console open "Store" and go to the "Redeem code" section.
2Enter the 25-character code from your order and confirm the activation on your own account.
3After the activation the code is shown as "Used" — but you can reinstall the game from your library at any time.

Notes for Xbox Series

Important

Do not change the password or the email of our account, do not disable two-factor authentication and do not activate Primary on several consoles at once — that blocks the access. Details are in the "Warranty" section.

How to play online
