Destructible surfaces change more than the shape of a room: they can create a route, open a sightline, or expose a position that seemed protected. In Rainbow Six Siege, attackers can use walls, floors, and hatches to threaten from another direction or level, while defenders use barricades, traps, and surveillance to shape how opponents approach. Every opening is a two-sided change: it may help a push, but it can also put the player who made or uses it in danger.
What destruction changes: routes, sightlines, and exposure
A breach can alter a round in three distinct ways. It may make a new path physically traversable, allow players to see or shoot through a surface without passing through it, or change which positions are exposed to observation and attack. Those effects are related, but they are not interchangeable. A visible opening is not necessarily a usable entrance, and a surface that can be shot through may still block movement.

Ubisoft’s early development article “Tools of Attack” describes Siege’s environments as moldable and discusses destruction as an attacking tool. Its “Launch Game Guide part 4” adds a practical distinction: some metal-stud walls and floors can be shot through but not traversed. That means players need to judge what an opening actually provides instead of treating every damaged surface as a doorway.
The tactical value of an opening depends on what it connects and who can exploit it. A breach might connect an attacker to a new approach, give a defender a view into a route, or let either side threaten a position from an unexpected angle. At the same time, the new line can reveal the person holding or crossing it. Destruction changes the information and risk available to both teams, not just the map’s geometry.

How attackers use openings to create flank pressure
Make a route that changes the direction of approach
An attacker can use a destructible wall or floor to create an approach that did not exist in the same form before. The point is not simply to make another hole: it is to make defenders account for pressure from an additional direction. If a team has been watching one approach, a new opening may force it to divide attention or reconsider where a safe position is.
That pressure is most useful when the opening has a clear purpose. Before creating it, consider what area it connects to, whether it allows movement or only a line of sight, and whether teammates can take advantage of the change. A breach that reveals a useful angle but leads nowhere can still affect a defender’s choices, but it is not equivalent to a safe entry route.
Use vertical pressure carefully
Floors and hatches can make another level relevant to the fight. Ubisoft’s launch guide describes surprise attacks through floor hatches, showing how vertical access can change where pressure comes from. A hatch can therefore matter even if the team is not immediately moving through it: its status and the possibility of access may affect how players judge nearby positions.

Access has to be real, not assumed. In Ubisoft’s 2019 guide to Amaru, a closed hatch must first be opened before her Garra Hook can ascend through it, and she is vulnerable during entry. That example illustrates two separate decisions: whether a hatch is open and usable, and whether the operator can survive the exposed moment of using it. It applies to that documented interaction; it should not be generalized to every operator or to ability details in later updates without current confirmation.
Do not confuse an angle with a safe entrance
A new sightline can create pressure without offering safe passage. Shooting through a surface, looking through an opening, and physically crossing it have different consequences. The player using a new angle may be exposed while checking it, and the defender may be able to respond to that exposure. Treat the opening as a change in available options, not a guarantee that the next move is safe.
How defenders shape positions—and why they must keep reassessing
Defenders are not simply waiting for attackers to remodel the map. Ubisoft’s “Tools of Defense” describes defensive setup through barricades, traps, and surveillance, emphasizing that both sides shape the environment. These measures can influence how opponents approach and what information defenders receive, but the map can still change as destruction creates new openings.

That makes defensive positioning conditional. A position that was protected by an intact wall or a limited approach may become visible or reachable after a breach. A barricade or surveillance setup can help shape a route, but it does not make nearby geometry permanent. When an opening appears, defenders should reassess whether their current position is still concealed, whether it can now be approached from another direction, and whether the information they relied on is still sufficient.

The useful habit is to respond to the changed map rather than continue acting as though the original defensive layout still applies. A new line of sight can make holding the same angle riskier; a new route can alter where attention is needed. The right response depends on the opening and the surrounding position, not on a fixed instruction to always move or always hold.
Read the surface before committing
Siege’s surfaces communicate information through their materials, but surface behavior is not uniform. Ubisoft Toronto’s map-modernization article discusses making materials readable so players can recognize a surface’s destructive or tactical potential. Ubisoft’s launch guide also notes that some metal-stud surfaces can be shot through without allowing traversal. Together, those points support a practical rule: learn to interpret surface cues, then verify what the surface permits before building a plan around it.

- Dive into the heart of the mission with Rainbow Six Siege Action.
- OFFICIALLY LICENSED UBISOFT GEAR
- Lightweight, Classic fit, Double-needle sleeve and bottom hem
- Ask what the surface can do: Is the relevant possibility movement, a sightline, or neither? Do not assume all walls and floors are destructible or behave alike.
- Identify what lies beyond it: Consider which area or level would be connected and who could use the resulting route or view.
- Account for the exposed moment: The player making or using an opening may become visible while doing so or immediately afterward.
- Recheck after the map changes: A new opening can change both the useful route and the risk attached to a position.
These checks are especially important when the plan depends on crossing a surface. The difference between “can shoot through” and “can pass through” is tactical, not cosmetic. Misreading it can leave an attacker without the route they expected, or cause a defender to treat a position as sealed when it is not.
A practical decision framework for an opening
Use the same four questions whether deciding to create an opening or responding to one. This keeps the decision focused on what the surface changes rather than on destruction for its own sake.
- What kind of access does it create? Determine whether the result is a traversable route, a sightline, or a surface that can be shot through but not crossed. The game’s surface behavior is not universal.
- What areas or levels become connected? Identify the spaces on either side and whether a hatch or floor opening introduces vertical pressure. A route matters because of where it leads.
- Who gains information, and who becomes exposed? An opening can reveal a position or change what either team can observe. Include the player making or using it in the risk calculation.
- What is the next move after it opens? Decide whether the opening is intended to support movement, create an angle, or force a defensive adjustment. If the intended benefit is unclear, the tactical value is unclear too.
This framework is a way to apply the mechanics Ubisoft describes, not a claim that any one opening guarantees a particular result. Its value is that it forces the decision-maker to weigh benefit and exposure together.

Attacking and defending: compare the trade-offs
The choice is not simply “destroy” versus “do not destroy.” Attackers may create pressure through an opening; defenders may shape the environment with setup and respond as the map changes. The comparison below describes tactical considerations, not measured success rates or guaranteed outcomes.
| Decision | Potential tactical value | Key risk or check |
|---|---|---|
| Create or use an opening | May add a route, sightline, or pressure from another direction or level. | Confirm whether it is traversable; the player making or entering it may be exposed. |
| Shape a defensive position | Barricades, traps, and surveillance can influence approaches and information. | A later breach can change which routes and angles threaten the position. |
| Hold a newly relevant angle | A sightline may affect movement even without providing a passage. | Do not mistake visibility for safe movement or assume the angle is one-sided. |
Ubisoft’s sources do not provide a sourced win rate, success rate, or frequency figure for these choices. The comparison is therefore about how the mechanics change decisions, not about assigning a numerical advantage to either side.
Build map knowledge without assuming every surface works alike
Map knowledge is more than memorizing room names or routes. It includes recognizing the materials and surface types that may be destructible or tactically relevant, understanding whether a particular surface permits traversal, and noticing how an opening changes the areas that can affect one another. Ubisoft’s map-modernization article frames readable material as a cue to destructive or tactical potential; the launch guide supplies the caution that shooting through and moving through are different capabilities.

When you see a potentially relevant surface, identify what you would gain from changing it and what exposure the change would create. When you encounter an opening during a round, update your understanding of the nearby routes and sightlines before relying on an earlier position as secure. This method stays useful even when exact map layouts or game balance change.
Older Ubisoft guides are useful for understanding these broad mechanics, but they are not a current competitive setup guide. They do not establish present-day layouts, reinforcement counts, operator loadouts, or balance outcomes. Those details should be checked against current in-game information when they matter to a specific map or operator.
Quick Recap
Common mistakes to avoid
- Assuming damage means passage: A surface may allow shots but not movement. Verify the route rather than planning around an unconfirmed crossing.
- Opening a surface without a purpose: A breach can change the map, but the team should know whether it is meant to create a route, an angle, or pressure that forces a response.
- Treating an opening as one-sided: The same new line that helps an attacker may expose the attacker or change what a defender can observe.
- Keeping a position on autopilot: A defensive setup does not eliminate the need to re-evaluate when a new route or sightline appears.
- Generalizing one operator example: The 2019 Amaru guide establishes a specific hatch interaction and vulnerability during entry, not universal hatch behavior for every operator or update.
