Recommendations below are strategic judgments rather than an official developer tier list. Some detailed tower behavior and map-specific advice comes from community references; where the evidence is incomplete, that uncertainty is stated.
Fast answer
The answer before the background
For a dependable campaign setup, open with Gun, add Inferno or Concussion where the path bends or bunches enemies, then specialize: Laser against fast or regenerating targets, Tesla against shields, and Cannon or Meteor on high platforms. Place Boost under the most valuable tower and select Disruptor when stealth or shielded enemies appear. There is no single permanent winner because tower limits, upgrade limits, alien composition, and pathing can change from one challenge or map to the next. The official manual confirms that challenge rules may restrict tower types, tower counts, upgrades, resources, aliens, cores, or map paths.
Direct comparison
Which towers deserve priority?
Verified: the game has ten tower types in its documented roster, including Boost, Gun, Inferno, Laser, Cannon, Temporal, Concussion, Meteor, Missile, and Tesla. Towers have unlimited ammunition, can be upgraded through three color-coded levels, and can alter alien routing by occupying build spaces.
Recommendation: rank towers by the job they perform rather than by raw damage. Gun is the best default because it is flexible and economical. Inferno and Concussion are the strongest broad answers to clustered enemies. Laser is the most reliable specialist for speed and regeneration. Cannon and Meteor become better as sightlines lengthen. Tesla is essential when shields are a major part of the wave, but less attractive as a general-purpose purchase. Temporal is excellent control when available, especially in a kill zone, but its value depends heavily on keeping enemies inside its range. Community references broadly agree on these roles, although they do not provide a standardized balance ranking.
| Tower | Best use | Main limitation | Priority |
|---|---|---|---|
| Gun | Early defense, shields, mixed waves, path shaping | Shorter range and weaker crowd damage than dedicated area towers | High |
| Inferno | Swarms, clustered enemies, damage over time | Needs enemies to stay near the field | High |
| Concussion | Close-range area damage and chokepoints | Less useful when enemies spread out | High |
| Laser | Fast aliens and regenerators; lingering damage | Does not solve every shield problem by itself | High when needed |
| Tesla | Shield removal and nearby area damage | Specialist value; weaker as a universal answer | Situational |
| Cannon | Long-range heavy single-target damage | Slow firing and poor stealth visibility | Medium-high |
| Meteor | Long-range area damage from elevated positions | Needs good sightlines and is vulnerable to stealth issues | High on open maps |
| Missile | Very long-range priority targets and tankers | Expensive and highly map-dependent | Medium |
| Temporal | Slowing enemies in a kill zone | Control tower rather than direct damage | Medium-high |
| Boost | Disruptor, Overcharge, or Score support | Requires another tower above it for full value | Very high support |
The official manual verifies the key interactions: projectile weapons are important against shields, Laser and fire are strong against fast aliens, constant damage helps against regenerators, and Boost’s Disruptor reveals stealth and helps disable shields. The ordering and tier labels are this guide’s recommendations, not official ratings.
Mode guide
Best choices by game mode
Story and standard campaign: use a balanced core rather than a one-tower build. Start with Gun to establish coverage and shape the route, then add one area tower and one specialist based on the Tactical Recon display. Save enough resources for upgrades instead of filling every slot immediately; the scoring system rewards surviving with cores and retaining resources, not merely building the maximum number of towers.
Challenge modes: read the rule card before choosing a loadout. If the mode limits tower types or upgrade levels, prioritize the tower that covers the largest number of threats under that restriction. A Gun-only or low-upgrade challenge favors careful placement and path length; an area-tower restriction makes Laser, Cannon, or Tesla more valuable depending on the alien list. The official manual confirms that challenge variants can change tower availability, counts, levels, resources, enemies, core behavior, and paths.
Coordinated Defense: divide responsibilities by function. One player should handle the opening route with Guns and shield coverage, while the other builds area damage, long-range towers, or Boost support on their assigned spaces. Build locations are divided between players, so avoid duplicating expensive specialists unless both lanes genuinely need them.
Doubles: agree on a shared kill zone. Put Boost under a high-value Cannon, Meteor, or Concussion, then coordinate Overcharge or Disruptor choices rather than scattering support towers. Doubles shares resources, score, build locations, and defensive planning, making a single efficient damage cluster preferable to two disconnected mini-builds.
DGFighter: favor reliable damage and flexible coverage over a slow greedy opening. Because kills can send stronger aliens to the opponent, Gun and Laser provide dependable wave clearing while Cannon or Missile can finish priority targets. This is a recommendation based on the mode’s documented escalation rule, not a verified tournament meta.
Map and placement
Match the tower to the map shape
Open maps and high platforms: prioritize Meteor and Cannon on elevated positions, with Boost underneath when the tower can cover several sections of the route. A community walkthrough specifically recommends this pattern on Overlook because grouped enemies and open fields create long firing opportunities.
Tight bends and looping routes: Inferno, Concussion, Laser, and Temporal gain value because enemies remain within range longer. Place area damage where the route compresses, not at the entrance where only a few targets are present. Use a Gun nearby if early waves include shields or mixed targets.
Multiple entrances: build a separate minimum defense for each lane before investing in a central kill zone. Gun is the safest first tower because it can cover mixed threats; add Tesla on the lane showing shielded enemies and Laser where fast or regenerating units are forecast. The manual confirms that Tactical Recon previews alien types and that shielded enemies can resist beam weapons until projectile damage removes the shield.
Stealth-heavy routes: do not rely on distant Cannon, Meteor, or Missile towers alone. The official help states that these long-range towers are practically unable to detect stealth at distance; place a Boost Disruptor so stealth targets are revealed within its area, then let the surrounding damage towers engage them.
Fixed-path maps: placement is about coverage and repeated exposure rather than maze construction. Put long-range towers where the path passes more than once, and use short-range damage at the most concentrated turn. On open-placement maps, a tower can also lengthen the route because aliens avoid its force field, so sell or reposition pieces when the path becomes inefficient.
Progression plan
What to build first as the campaign expands
Early progression: learn with Gun, Inferno, Laser, and Boost. This four-tower foundation teaches the game’s main checks: mixed damage, crowd control, lingering damage, and support. Do not rush level-three upgrades on every tower; one well-positioned upgraded tower usually does more work than several underfunded purchases. The manual confirms that red-level towers are substantially stronger but very expensive.
Mid-campaign: add Tesla when shields become common, then develop Cannon or Meteor for maps with platforms and long sightlines. Concussion becomes increasingly useful when routes can be compressed. A community mission guide reports that later Chapter 2 missions introduce larger tower selections and specifically recommends damage-over-time towers for regenerators, Tesla for shields, and Meteor for multi-target damage.
Late campaign and Aftermath: expect broader layouts and more specialized threats, so keep the balanced core but change the support choice per wave. Steam describes Aftermath as five additional story missions; the Switch listing also includes five Aftermath missions in its 26-mission campaign package. Exact availability depends on edition and platform, so check the in-game mission list rather than assuming the DLC is included.
For score chasing: use Score Boost only after survival is stable. The official scoring explanation says kills are affected by cores, resources on hand, and tower investment, so overspending can hurt the result even when the defense succeeds.
If two towers seem close, place them in comparable positions, upgrade them at similar times, and inspect which one is actually contributing damage. This is especially useful because range, path exposure, target type, and upgrades can matter more than a simple damage-per-shot comparison.
Common questions
FAQs about tower selection
FAQ
Common questions
Is Gun the best tower for every mission?
No. It is the safest general-purpose and early-game tower, but Inferno or Concussion is better against dense groups, Laser is better against fast or regenerating enemies, and Tesla is better when shields dominate. Treat Gun as the reliable foundation rather than the universal endgame answer.
Which tower should go on a Boost tower?
Use Disruptor under a tower cluster when stealth or shields are a problem, Overcharge under your highest-impact damage tower when survival is the priority, and Score Boost only when the defense is already secure and you are optimizing points. Boost’s exact benefit is verified by the official help; the priority order is a recommendation.
Are Meteor and Missile interchangeable?
No. Both reward range and clear sightlines, but community references describe Meteor as the area-damage option and Missile as a costly single-target choice. Use Meteor for grouped enemies and Missile for high-health priority targets when the map gives it enough time to fire.
What counters regenerating aliens?
Keep continuous damage on them with Laser, Inferno, or Concussion, and avoid relying only on slow burst attacks. The official manual says regenerating aliens can heal when they are not taking damage, while a mission guide recommends damage-over-time towers for this threat.
Should I build Tesla at the entrance?
Usually, yes, when shielded aliens are announced early: removing shields lets the rest of your weapons deal full damage. If the wave has no meaningful shield threat, spend that slot on Gun, area damage, or support instead. Beam weapons can be ineffective or less effective against intact shields according to the official manual.
