Contain is a first-person tactical shooter focused on methodical engagements, realism, and player choice. If you want, you can play the missions offline, solo, or you can progress by forming co-op teams with your friends.

You are part of a special task unit within a secret organization assigned to contain objects of extraterrestrial and supernatural origin. Every mission consists of high-risk operations that require tactical planning and execution. Right gear, positioning and coordinated actions matters more than reflexes.

A NEW BEGINNING: Project Genesis

Our content update in January 2026 brought a huge transformation to Contain. Whether you’re returning to the field as a seasoned operator or stepping in for the first time, you now play a reborn Contain, hence the name Genesis.

With the game code written fully from scratch, Contain:Genesis pushes our operational capabilities beyond the limits. We have areas that have been rebuilt from top to bottom, visually and audibly overhauled, with increased atmospheric intensity. The mission zones you thought you knew are now far more unsettling, each shadow hiding a different threat. The improvements coming with Genesis make every moment more realistic and more tense — from how you hold your weapon to how you take each step.

YOUR OPERATOR, YOUR CHOICE

Weapon Customization Contain features Gunsmith, a detailed weapon modification system. On your weapons, you have full control over:

• Barrels, suppressors, optics, and grips

• Tactical attachments and accessories

• Weapon handling feel and performance

Each part serves a specific purpose and lets you shape your weapon to match your playstyle.

Pistol Customization

With Genesis, pistols have also become customizable.. You can now equip attachments such as suppressors.

Character Customization

Every bullet you carry, every med kit you take, and every grenade you choose shapes the decisions you will make during the mission. Your gear determines the rhythm of the firefight; define how far you can push, when you need to take risks, and when you need to fall back. With Contain: Genesis, our armory has expanded even further with more weapons and new parts to modify them.

CO-OP GAMEPLAY

You can play Contain solo or form a Fire Team with up to 5 people. Role distribution within the team, synchronized movement, and clear communication play a critical role in completing missions successfully.

There is zero margin for error. Friendly fire, communication breakdowns, or poor positioning can result in the entire team being wiped out.

Choose your team well and practice in the renewed Training Area beforehand.

GET READY, OPERATOR.

TARGETS MARKED.
