Plastanium Wall

Plastanium Wall is a defensive block that protects friendly structures by blocking incoming projectiles and absorbing certain energy weapons. It exists in small and large variants; both can stop lasers and Arc effects, and they also prevent Power Nodes from automatically forming connections through them. The wall is commonly used to shield ammo lines, power infrastructure, and other vulnerable blocks from direct fire or directed-energy attacks.

Small Plastanium Walls have notably low health compared to the large variant and perform much worse even when tiled (four small walls over a 2×2 area are still weaker than one large wall). High-damage units such as Vela, Corvus, or Navanax can destroy small Plastanium Walls extremely quickly; Corvus can remove small walls in a single hit. Small walls also receive far less effective healing from Menders and Mend Projectors, making breaches easier and increasing the risk that piercing weapons will hit behind the wall. Against lower-damage enemies like Pulsars or Oxynoes, small Plastanium Walls are a cost-saving option when placed behind a stronger outer layer to conserve Metaglass, Plastanium, and floor space.

Plastanium Walls interact with power and beam systems in specific ways. They block automatic connections between Power Nodes, and they can intercept beam links from Beam Nodes and Beam Towers; intercepted beam connections cannot be restored manually while the wall remains in place. This interception can be leveraged defensively or used deliberately in power-routing strategies. Placing Battery Diodes in conjunction with Plastanium Walls lets you enforce unidirectional power flow and prevent other nodes from bypassing your intended routing.

Beyond lasers and arcs, Plastanium Walls can absorb certain weapon projectiles: they stop Fuse secondary bullets and the secondary projectiles of Toxopid, preventing further penetration from those sources. This makes them especially useful against mixed-energy attack compositions that include both beam and splinter projectiles.

• Use large Plastanium Walls on frontlines where concentrated, high-damage units are expected; reserve small walls for secondary lines or behind stronger barriers.
• Combine with Menders and Mend Projectors but rely more on large walls for effective automated repair; do not expect small walls to hold under focused fire even when healed.
• Employ Battery Diodes and wall placement to control node connectivity and create one-way power networks, especially to protect sensitive generators or ammo lines.
• Use walls to intentionally intercept Beam Node/Beam Tower links when you need to sever or reroute beam chains; remember intercepted beams cannot be manually reconnected while blocked.
• To save resources, place small Plastanium Walls behind another material layer to absorb stray low-damage fire while preserving Metaglass and Plastanium for critical structures.
