Arcfence: tower defense

The piece you place is the wall. The enemy's path is born from what you left open.

There is no track drawn on the ground. The field opens empty, with rock and a core to defend, and it is your walls that decide where the invader walks: it always takes the shortest way that is left. Drawing a long, winding corridor is the whole game.

And here is the rule no other game in the genre has: you CAN seal the passage completely. When you do, the invader stops walking and breaks the piece that seals it. Sealing buys time and costs the wall. It is a real decision, taken mid-wave, with the piece sinking in front of you.

SEVEN PIECES, EACH SOLVING A DIFFERENT PROBLEM

Wall is cheap, takes a lot of punishment and does not shoot: it is the maze and it is what you sacrifice when you seal. Autogun handles many weak invaders. Mortar hits an area but has a MINIMUM range: it cannot hit what is right next to it, so it must sit back. Laser pierces everything in line, which rewards a straight stretch and fights the serpentine you want to build. Slower deals no damage at all: it brakes, multiplying the time an invader spends under everything else. Workshop sends a drone to repair damaged pieces nearby. Barracks trains soldiers who head down the corridor and fire at the horde early.

Each one upgrades to level 3. An upgraded wall gets thicker and survives more biting; an upgraded gun hits harder. And the number of guns per level is capped: the decision is WHICH family and what to upgrade, not filling the field with turrets.

YOU SEE THE EFFECT BEFORE SPENDING

Hold your finger on a cell and the game tells you how many steps that piece will add to the path, before you pay for it. If the piece diverts nothing, it says so and explains why: a lone wall diverts nothing, so you have to close a line.

SIX KINDS OF INVADER

And the SAPPER, from the later waves, is the only one that does not respect the corridor: when going around gets expensive, it breaks the wall and goes through. It is what makes the maze something to defend, not just something long. The SHIELDED one carries a shield that only the laser gets through. The GUNNER stops and fires at your guns, and the gun under fire shoots back.

Machines, not creatures. The common one comes in numbers. The fast one trades toughness for speed and crosses your range before dying. The heavy one absorbs concentrated damage and walks slowly.

EIGHTY LEVELS THAT WERE MEASURED, NOT GUESSED

Every level was played start to finish by a simulated player and tuned until it cost the right number of core lives. There are 80 fields, one design per level, in four sectors, each with its own spatial question:

PERIMETER (free, 20 levels): where the maze begins. Open field, narrow corridor, two entrances, rock chokepoint, long field, core in the corner, rift and arena.

FURNACE: the squeeze. Tight fields, room for few guns, every wall costing double. The question is where NOT to build.

OPEN SKY: the flow. Big fields and more than one mouth. Space to spare, time running out.

BREACH: the asymmetry. The core is rarely at the end of the axis, and the layout that always worked will not work twice.

And when the levels run out, ENDLESS mode keeps going: on a map you have already beaten, the waves never stop and what counts is how long you hold.

Four difficulties; the levels were tuned on Normal.

NO CATCH

No ads. No energy to wait for. No in-game currency, no loot boxes, nothing you can buy to get stronger. The Perimeter sector, with 20 levels, is complete and free: you can play from the tutorial to the end without paying anything. The other three sectors are a one-time purchase and bring only new levels, all measured as beatable. No account needed. The game only talks to Google Play: to check and make purchases and, just once, to ask for a review.

Six languages. Landscape, with the piece panel on the side.

Single player. Plays with no internet.
