Build a neon defense that works together. Place six tower types, combine their strengths, and adapt as enemy waves push through the grid. Try five campaign levels free, then unlock the full campaign with one purchase. FAIR PRICING Try the first 5 levels free. One single purchase unlocks all 30 levels, boss fights, and every future update — forever. No subscriptions, no consumables, no ads. Roguelite, survival, and weekly challenges are free for everyone. Core gameplay runs fully offline; a connection is only needed for the one-time purchase, Game Center, and iCloud sync. 30 CAMPAIGN LEVELS x 3 DIFFICULTIES Battle through 30 handcrafted levels across 3 acts. Play on Normal, Hard, or Insane - each difficulty scales enemy HP, speed, and your starting economy. Earn up to 3 stars per level and accumulate Voltage to unlock tower tiers, abilities, modes, and color schemes. Every level is hand-designed with unique grid layouts, enemy compositions, and strategic chokepoints. EPIC BOSS ENCOUNTERS Face the boss on late-game levels as it cycles through vulnerable and shielded phases - the same relentless standoff every time, demanding sharp timing and the right tower placement to break through. One wrong move and the grid falls. ROGUELITE, SURVIVAL & DAILY CHALLENGES Start a roguelite run with EMP and one random tower, then draft your next tower every 3 waves from a curated selection of three choices. Every 5 waves the map rotates and a modifier shakes up your approach, so no two runs play the same. Endless survival mode tests your endurance against infinite escalating waves. Daily and weekly challenges set the same fixed level, difficulty, and modifier for everyone - compete on Game Center leaderboards. TOWER SYNERGIES & ACTIVE ABILITIES Six tower types - Laser, EMP, Firewall, Tracer, Grid, Pulse - each with 3 upgrade tiers and branching specializations. Pair adjacent towers to trigger five synergies: Cryo-Burn, Ionized Grid, Suppression Field, Overcharged Lattice, and Kinetic Relay. Command the battlefield with deployable abilities that charge as you fight: Slow Field slows every enemy on the grid for a few seconds, buying you time to reposition and chain your towers' synergies. BUILT FOR ACCESSIBILITY Colorblind mode adds geometric symbols on every tower and pattern-fill HP bars, not just color. Reduced Motion simplifies animations, and a Flashing Effects toggle turns off strobing and flash-based effects for photosensitivity. Larger Text offers three text sizes, up to 1.5x standard. VoiceOver support covers menus, HUD, and tower panels, plus a board overlay that reads out every grid cell so you can place and select towers by touch.

Verdict

The call

The clearest difference is ads: Voltline at none against Skeleton Heroes's shown. Skeleton Heroes's advantage is update cadence (every 10 days vs every 4 weeks) and iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
