Corrode is one of the most unique maps in Valorant, blending northern French salt marshes with an ancient castle converted into an industrial facility. The map features an island-like layout, rich verticality, and three main lanes connecting two spike sites (A and B), making each round a complex tactical encounter. This guide breaks down the map by spike site, providing a detailed analysis of layout, combat strategies, and team positioning.
▍Spike Site A: Salt Marsh Heights and Castle Entrance
Site A is located on the left side of the map and is characterized by long sightlines and elevated positions, with multiple access routes for attackers.
- High Ground Advantage: Elevated platforms provide natural vantage points for snipers and long-range firepower. Controlling these areas allows players to suppress pushes while monitoring mid-lane and flanking routes.
- Mid-Lane Pressure: Routes connecting Site A to mid are critical. Players can deploy smokes or obstacles to obscure enemy vision, slowing down pushes and supporting teammates for coordinated engagements.
- Flanking Routes: The outer flank of Site A offers opportunities for enemies to attempt backstabs. Setting traps, deploying utility, or positioning a long-range player can delay enemy advances.
- Balanced Attack and Defense: Players can use high ground to apply pressure while simultaneously covering nearby chokepoints. This setup allows a site to be defended effectively while remaining capable of initiating pushes.
▍Spike Site B: Castle Interior and Industrial Facilities
Site B is located on the right side of the map and is tighter, with narrow corridors and abundant cover, emphasizing close-quarters combat and utility usage.
- Narrow Corridors and Cover: Tight pathways limit movement, making skillful utility deployment essential. Offensive players must use flashes and smokes to advance, while defenders can use Molotovs, slows, or traps to block entry.
- Vertical Advantage: B site has a few high points that can be used to suppress enemy movement. Players can switch between angles to gain an advantage over attackers.
- Cover and Wall Usage: Industrial structures and walls act as natural barriers and skill deployment zones. Attackers can use them to safely approach the spike, while defenders can block sightlines and slow the push.
- Retake Opportunities: Because of narrow entryways, B site can be quickly contested if lost. Utilizing mid-lane rotations or side corridors for retakes, combined with skill and gunplay, is crucial.
▍Mid-Lane and Rotation Strategy
Mid-lane is the strategic hub of Corrode, linking both spike sites and enabling fast rotations.
- Vision Control: Elevated positions and open lanes allow players to monitor enemy movements while providing support to either spike site.
- Rotation Efficiency: Controlling mid enables rapid reinforcement of Site A or B. Maintaining mid control pressures the enemy and forces them to split their team.
- Utility Combinations: Mid contains thin walls and multiple levels of cover, making it ideal for combining reconnaissance (Sova, Cypher) with control abilities (Omen, Brimstone) to create attack or defense opportunities.
▍Recommended Agent Compositions
Corrode requires a balance of information gathering, firepower, and control due to the combination of long-range and close-quarters combat:
- Long-Range and Suppression: Jett and Neon excel on high ground and narrow corridors, providing flexible firepower across sites.
- Recon and Information: Sova and Cypher are key for monitoring mid-lane and spike entrances, keeping the team informed.
- Control and Delay: Omen and Brimstone can smoke off chokepoints, creating opportunities for teammates to reposition.
- Burst Damage and Site Entry: Raze is ideal for close-quarter explosive engagements, especially when paired with other skill-heavy agents.
- Stable Defense: Sage can use walls and slows to block key routes, providing time for retakes or holding sites.
▍Conclusion
Corrode is defined by its three-lane, two-spike site layout, island-style compact map structure, and varied verticality. Site A offers a mix of long-range and positional gameplay, while Site B emphasizes tight spaces and utility engagement. Mid-lane serves as the pivotal rotation hub, influencing both offense and defense. Mastering high ground, chokepoint control, and utility placement is essential to dominate Corrode. Teams that understand the map layout and coordinate effectively will leverage each agent’s strengths to control the battlefield.
