Cover the exit
Keep dependable priority fire near the escape route. Add area or siege damage for swarms, then adapt your control towers to speed, shields, and armor.
XenoDefense field strategy
TOWER
PROFILES
Choose the right weapon for the route. Combine damage, control, and support to keep the swarm inside your strongest defenses.
Build a formation
that works together.
Make the path work
Favor bends, intersections, and places where a route returns to tower range. Slow enemies inside overlapping fire rather than away from your damage.
Support with purpose
Center auras on compatible, valuable towers. Support towers do not augment each other, and only the strongest aura for each stat applies.
Direct · Physical
Xeno Ray
Fast, inexpensive priority fire. A dependable foundation for the opening defense and for catching enemies that escape heavier weapons.
Placement & strategy
Build beside a long path segment and keep dependable coverage near the exit. Pair with Dread Ray so light enemies do not consume its heavy shots.
Level IV transformations
Available when the battlefield allows this upgrade level.
Gatling Tower
Rapid fire with a brief slow on enemies it hits. Use it to hold runners under overlapping fire.
Xeno Needle
Rapid fire and raised damage, with longer reach. Choose it when extra coverage helps your formation.
Direct · Radiant
Dread Ray
Heavy, deliberate shots against durable priority targets.
Placement & strategy
Cover a long approach and focus tough enemies. Keep faster damage towers nearby to handle light targets between heavy shots.
Level IV transformations
Available when the battlefield allows this upgrade level.
Dreadstar Ray
Raised damage with a chance to stun. Use it against durable threats while the rest of your defense covers runners.
Direct · Radiant
Monolith Laser
A close-range laser that builds devastating damage through uninterrupted exposure to the same target.
Placement & strategy
Place it where a durable enemy stays in reach. Pair it with Stasis Radiator to extend exposure, and avoid unnecessary target changes: losing or switching targets resets its damage ramp.

Damage over time · Necrosis
Necron Cannon
Sprays enemies with necrosis-inducing poison. Longer exposure builds a stronger effect, and decay continues after enemies leave the spray.
Placement & strategy
Cover long path segments to keep the spray connected. Use slowing effects to prolong exposure, with reliable exit coverage to finish survivors.
Level IV transformations
Available when the battlefield allows this upgrade level.
Necron Spire
Replaces the spray with a close-range field that continuously damages and slows enemies while draining their current health. Place it where enemies remain exposed.
Area · Physical
Spore Emitter
Damages groups inside its surrounding cloud. Sustained crowd exposure makes it especially useful against swarms.
Placement & strategy
Place at bends or intersections where enemies stay within the cloud. Pair with Stasis Radiator to hold groups in range, or Melting Tower when armor blunts its damage.
Back to tower index ↑
Chain · Radiant
Lightning Conduit
Chains lightning through enemies in range, spreading damage across a formation.
Placement & strategy
Choose a position where enemies arrive together so the chain can find additional targets. Pair with Void to make exposed Lightning Bugs vulnerable to its attacks.
Level IV transformations
Available when the battlefield allows this upgrade level.
Lightning Bolt
Adds a powerful targeted chain against surface enemies across the board. Use its reach to answer pressure beyond your local defenses.
Siege · Physical
Xeno-Missile
Long-range splash damage for clustered waves.
Placement & strategy
Aim across long lanes and use slows to keep groups together before impact. Keep a faster tower nearby to clean up isolated runners.
Level IV transformations
Available when the battlefield allows this upgrade level.
Xeno Nuke
Launches a huge blast and leaves a radiation field behind. Favor busy routes where both the explosion and lingering field can contribute.
Siege · Radiant
Obelisk Mortar
Predicts a future path tile and leaves a damaging hazard at the impact site.
Placement & strategy
Cover predictable, busy path segments. Slows help enemies remain inside the impact area and lingering hazard.
Level IV transformations
Available when the battlefield allows this upgrade level.
Fire Mortar
Adds stronger damage and lingering flames that burn enemies and weaken armor. Combine the burning area with overlapping tower fire.
Degrader · Slow
Stasis Radiator
Slows unshielded enemies, extending the time they spend under your towers’ fire.
Placement & strategy
Place its aura around your strongest kill zone. Pair with Monolith Laser, Spore Emitter, or siege towers. Active shielding prevents the slow; use Void on protected enemies or their Shield Bug source.
Back to tower index ↑
Degrader · Suppression
Void
Suppresses enemy healing, acceleration, and shielding. It also slows exposed Lightning Bugs and makes them vulnerable to Lightning Conduit.
Placement & strategy
Cover support bugs to disable their full aura, or cover their allies directly to strip augmentations. Combine with Stasis Radiator to slow formerly shielded enemies, and with Radiant towers against exposed resistant threats.
Back to tower index ↑
Degrader · Armor suppression
Melting Tower
A short-range aura that makes enemy armor less effective.
Placement & strategy
Build beside a compact kill zone where armored enemies remain exposed. Physical damage towers benefit most, making Xeno Ray, Spore Emitter, and Xeno-Missile useful partners.
Back to tower index ↑
Support · Fire rate
Accelerator Node
Increases the firing rate of compatible towers within its aura.
Placement & strategy
Cluster slow or high-impact weapons inside its aura to gain more attacks from the same formation. Spread coverage instead of overlapping duplicate fire-rate boosts.
Back to tower index ↑
Support · Damage and impact
Surge Relay
Improves damage or effect impact for compatible towers in its aura.
Placement & strategy
Center it among towers that fire often or hit groups. Invest where the boost benefits an established formation, and avoid redundant damage auras.
Back to tower index ↑
Support · Range
Horizon Lens
Extends the range of compatible nearby towers.
Placement & strategy
Use it to let short-range weapons cover more path or reach another lane. Favor positions where the added reach creates useful coverage rather than empty space.
Back to tower index ↑
Support · Fire rate and damage
Nexus Core
Combines fire-rate and damage boosts in a shared aura. It does not increase range.
Placement & strategy
Anchor a dense, valuable cluster of complementary towers. Pair with Horizon Lens when range is the missing piece; duplicate boosts to the same stat do not stack.
Back to tower index ↑
Economy · Biomass
XenoPump
Extracts biomass from an adjacent liquid feature instead of attacking enemies.
Placement & strategy
Place beside water, acid, or lava once your defense can hold. Protect the investment while it funds later construction and upgrades; preserve damage coverage before expanding your economy.
