What Is the Siege Game? Rainbow Six Siege X Explained

The “Siege game” usually means Tom Clancy’s Rainbow Six Siege, Ubisoft’s tactical first-person shooter. Its current major evolution is branded Rainbow Six Siege X. The core experience is a tense 5v5 contest: Attackers use drones, gadgets, and breaches to reach an objective, while Defenders fortify it and try to stop them. Rather than relying on speed alone, Siege rewards information, map knowledge, careful aim, and teamwork.

Siege X keeps that familiar attacker-versus-defender format and adds other ways to play, including the separate 6v6 Dual Front mode. The game also has a permanent Free Access option, so new players can try selected playlists without buying a premium offer.

Rainbow Six Siege at a glance

How the core 5v5 Siege match works

A standard round pits five Attackers against five Defenders inside a building or other close-quarters map. The sides switch during a match, so each team has to demonstrate both how to enter a defended area and how to protect one. In many core playlists, the main objective is Bomb: attackers locate a bomb site and try to plant and protect a defuser, while defenders prevent the plant or disable the device after it is set.

Rounds begin with a brief preparation period. Defenders reinforce selected walls, place equipment, and set up their positions. Attackers send small camera drones into the building to search for the objective and identify threats. When the action phase starts, attackers choose an entry route and push in; defenders can hold the site or reposition to challenge them.

Most core rounds do not give eliminated players a quick respawn. Losing one teammate can change the balance of a round, so rushing through a doorway without checking it is risky. Teams can also win by eliminating the opposing side, but gathering information and completing the objective often matters more than chasing eliminations.

Ubisoft describes the central experience as tactical 5v5 attack-versus-defense gameplay with Operators and destructible environments. Its official Siege overview is a useful place to see the game’s current features.

Operators make every round play differently

Before a round, each player chooses an Operator, a named character with a specific ability, weapons, and equipment. Operators are grouped by role: attackers tend to bring tools for scouting, opening routes, or pressuring defenders, while defenders use tools to reinforce, detect, slow, or deny an attack. Choosing a useful combination with your team is part of the strategy.

For example, one attacker might use a drone to confirm that a room is clear, while a teammate brings equipment to open a soft wall. A defender might reinforce a key wall and use a gadget to watch a doorway. These are different jobs within the same round, not separate character classes that lock players into one weapon or play style.

You do not need to learn the entire roster before playing. Pick one or two Operators whose abilities make sense to you, learn when to use their gadgets, and expand your choices as you recognize what your team needs.

Destruction changes the map and the tactics

Siege maps are not fixed boxes. Many soft walls, floors, hatches, and barricades can be damaged or opened, creating new routes and lines of sight. Attackers may breach a wall to enter a room or break a floor to apply pressure from above. Defenders can reinforce important walls, which makes those sections much harder to breach.

That destruction makes sound and positioning especially important. A wall that gave you cover a moment ago can become an opening, and a loud breach can reveal where an attack is coming from. Look for new holes, listen for footsteps and gadget sounds, and avoid assuming that a familiar room is still safe. Not every surface is destructible, and reinforced barriers change what an attacker can do.

What is Siege X, and what is Dual Front?

Rainbow Six Siege X is the name Ubisoft uses for the game’s major evolution, launched on June 10, 2025. It was introduced as an update for existing players, with progression and inventory carried forward. The familiar 5v5 attack-and-defense format remains the main identity of Siege.

Siege X also includes Dual Front, a separate permanent 6v6 mode. It mixes Attack and Defense Operators on each team and centers on capturing enemy sectors while defending your own; matches also include respawns. That makes Dual Front a different kind of match from the round-based 5v5 core mode. Ubisoft’s Siege X and Operation Daybreak overview explains the mode and the Free Access model.

Is Rainbow Six Siege free, and where can you play it?

Ubisoft’s current Free Access offer lets new players enter Quick Match, Unranked, and Dual Front with a selection of Operators. Ranked, Siege Cup, additional Operators, and cosmetics require a paid offer or upgrade. The exact content available can change, so check Ubisoft’s Free Access page for the current terms instead of relying on an old price or edition list.

Rainbow Six Siege is available on Windows PC, PlayStation, and Xbox. Ubisoft lists PC storefronts and console generations in its platform availability guide; Dual Front is not supported on PlayStation 4 or Xbox One. The game supports cross-play and cross-progression across supported platforms, with platform-specific details in Ubisoft’s cross-play and cross-progression support article.

How to start playing Siege as a beginner

• Complete a tutorial or training activity. Use the built-in onboarding to learn controls, gadgets, and the basic objectives before joining a live match.
• Start with Quick Match. It gives you room to learn the pace and maps before you try Ranked. Unranked is another option when you want a more structured match without jumping straight into competitive play.
• Use your drone before entering. Even a quick look at the next room can prevent a blind push and help your team choose a safer route.
• Make simple callouts. Share an enemy’s location, a newly opened wall, or the room you are watching. Short, accurate information is more useful than constant chatter.
• Reinforce with a purpose. On defense, reinforce walls that help protect the objective, and leave useful rotations or teammate routes open when your team needs them.
• Expect to learn gradually. Maps, sound cues, Operator abilities, and sightlines take time. Review what exposed you after a round and adjust one decision at a time.
