About Ion Warden Grid
Ion Warden Grid is a chain-lightning tower defense puzzle. A storm emitter sits at the bottom of the arena. Storm skills auto-cast from the emitter whenever the charge meter is full — you do not aim or fire manually. Your job is to spend skill points to upgrade four skills so the automatic storm can handle every wave.
The game spans 50 levels. Each level spawns a set number of minions (500 + 10 per level) in batches, with a boss arriving near the final third. If any enemy reaches the emitter line, or the timer runs out before all enemies are cleared, the level fails. Clear every minion and the boss to win.
Four skills can be upgraded with skill points: Link (adds chain targets and range), Nova (periodic area burst around a target), Field (a horizontal static line that slows and damages enemies), and Rate (a focused single-target surge that prioritizes the boss). Each skill has 8 upgrade levels with increasing cost.
How to Play
Start a Level
Tap Start Storm on the main menu to continue from your highest unlocked level, or visit Levels to pick any unlocked stage.
Watch the Charge Meter
The storm auto-casts an Ion Arc chain when the charge meter is full. The meter refills automatically over time.
Earn Skill Points
Each destroyed minion grants 1 SP. Defeating the boss grants a bonus 10+ SP. Starting SP scales with level (100 + level − 1).
Upgrade Skills
Tap the Link, Nova, Field, or Rate buttons at the bottom to spend SP. Each upgrade increases damage, range, or frequency.
Hold the Line
Do not let enemies reach the emitter line at the bottom. A breach ends the level immediately.
Beat the Boss
The boss arrives near the final third of the level. Clear all minions and the boss before the timer runs out to win.
