The First Wave

It Starts Quiet...
Then They Arrive

At first, it's just a grid. Weapons scattered across it — waiting, inactive, silent. Then the monsters appear.
Slow at first. Almost harmless. Moving toward your line like they don't expect resistance.

But they do. And you're the only thing standing between them and everything behind you.

The System

You Don't Shoot.
You Connect.

There's no trigger to pull. No direct attack.
Instead, you align.

Weapons of the same type — placed carefully into straight lines. Horizontal. Vertical. Clean. Precise.

And when they connect... They transform.

Get the alignment right and boom — those tiny weapons hit like trucks.
And the attack launches automatically.

The Pressure

The Grid
Doesn't Wait

The longer you play, the faster it becomes.

More monsters. Stronger waves. Less space to think.

You start making faster decisions. Choosing between quick survival or building something bigger.

One wrong move doesn't always end the game.
But a few of them... will.

How It Works

Every Move Is a Decision

You don't have unlimited time. Every placement matters.

01
Match Weapons
Match identical weapons into horizontal or vertical lines to activate them.
02
Create Combos
Chain longer lines for stronger attacks. The bigger the combo, the harder they hit.
03
Manage Space
Clear space or build bigger strikes — your grid is always limited. Use it wisely.
04
Stop the Wave
Stop monsters before they cross the line. Let one through and the pressure doubles.
You're not just solving a puzzle. You're holding a defense.

FAQ

Frequently Asked Questions

Everything you need to know before the first wave.

It's a hybrid of puzzle and defense gameplay. You match weapons to create attacks that automatically strike incoming enemies. You'll find yourself juggling quick decisions with longer-term strategy. It's easy to understand but gets intense quickly.
At the beginning, not really. The early waves are slower and give you time to learn. But as you progress, the pace increases and quick thinking becomes important. You'll naturally adapt over time.
Yes, balancing is key. You can either clear space quickly or build larger combos for stronger attacks. Knowing when to go for the big combo vs. just clearing space — and honestly, that's where you'll see the difference between players who really get it and those who don't. There's no single correct way to play.
Your health decreases when enemies cross your boundary. If it reaches zero, the run ends. You'll need to start again and try a new strategy. Yeah, you'll mess up and it's annoying, but that's how you learn what works.

How Long Can You
Hold the Line?

There's always another wave.
Another combination. Another moment where everything could go right — or collapse completely.

The grid is never fully under control.
But for a few seconds... it can feel like it is.
