Robot Series Packs 19–21: Outpost Kit Tileset, Final Bosses and Effects
An isometric pixel art tileset for Godot 4 and Tiled, three 192 px final bosses and 23 pixel art effects: explosions, projectiles, shields, heals and more.




The last three packs
Packs 19 to 21 complete the Robot Series at 21 packs. After the characters, they add what a level needs around them: an isometric tileset to build the world, three final bosses for the last fight and a set of pixel art effects for every shot, hit and explosion.
They keep the palette, light from the upper left, 1 px outline and 2:1 isometric grid of the robots, so everything from Packs 1 to 21 fits in the same scene.
Pack 19: Outpost Kit, an isometric pixel art tileset
A sci-fi outpost kit with 216 pieces and 355 frames on a 2:1 isometric grid with 64x32 tiles. The robots of the series stand on a tile at the same scale. It comes with a ready-made Godot 4 TileSet with terrains, animated tiles and Y-sort origins, tested in Godot 4.5, and with Tiled tilesets with wang sets, plus the same demo map for both. Free sample: 22 pieces, including floors, a metal wall with an animated lamp, a crate in 3 states and animated pickups.

- Floors (118): 24 single tiles (dirt, gravel, dry grass, concrete, metal plates, grating, hazard stripes, oil, scorch marks, a drain, a landing pad, cables, an animated light strip and fan vent) and two 47-tile auto-tile sets: a metal platform with hazard tape and concrete with a kerb.
- Walls (56): two 16-piece auto-tile wall sets (metal and concrete) with corners, T-junctions, crosses and ends, 16 wall modules (lamps, screens, windows, vents, pipes and more), 2 animated doors, low cover, sandbags, rock walls and a pillar.
- Props (29): crates and barrels in 3 states (intact, damaged, destroyed), explosive and toxic barrels, a container, a generator, a terminal, a radio mast, a satellite dish, fences, rocks and more.
- Pickups (13): coin, crystal, small and big repair kits, ammo, energy cell, shield, power-up, extra life, upgrade chip and 3 keycards.

Pack 20: Final Bosses
Three huge boss sprites for the last fight of an isometric game, on 192 px cells, the biggest in the series: a 64 px robot stands about knee-high to them. Each boss has 8 or 9 animations in 8 directions, including a rage animation for the phase change halfway through the fight: 2,496 frames in total. The README lists the key frames of every attack, so you know where to deal damage. Free sample: Scrap-Golem, with idle and walk in 8 directions.

- Dragon-Mech: a four-legged mechanical dragon with membrane wings and a chest furnace. Bite, tail whip and a firebreath that ends in a burning pool; in rage it rears up and roars.
- Kraken-Bot: an armoured kraken that travels under the floor and bursts out of it. Tentacle slam, grab and an eruption of tentacles from the ground; in rage its armoured doors open on a glowing core.
- Scrap-Golem: a giant made of junk held together by a magnetic core. Ground smash, crate throw and a magnet storm of scrap; in rage it falls apart and pulls itself back together.

Pack 21: Effects, 23 pixel art effects
23 animated pixel art effects for action games, 350 frames in all, on cells from 32 to 128 px. Projectiles and muzzle flashes come in the 8 directions of the isometric grid. They use the series palette, but they work in any pixel art game. Every effect has a sprite sheet, single PNG frames, a JSON file with cell size, anchor point, timings and loop flag, an Aseprite source and a Godot 4 SpriteFrames resource, one animation per direction. Free sample: small explosion, bullet and bullet impact.

- Explosions: small explosion, big explosion with debris and a shock ring, plasma explosion and a ground shockwave.
- Projectiles in 8 directions: bullet, laser, plasma ball and rocket, plus a muzzle flash.
- Impacts: bullet impact, laser impact, plasma impact and metal sparks.
- Elements: lightning strike, smoke puff, dust and fire.
- Abilities: teleport out, teleport in, shield, shield hit, heal and a sparkle for pickups.

Effects that chain together
The effects are made to be combined: a muzzle flash at the gun, a projectile in flight and the matching impact where it lands, or a rocket that ends in a big explosion. The shield loops while it is up and plays its hit animation when it is struck; the teleport pair tells you on which frame to hide or show the character.
The demo below shows them at work between Trooper-Bot from Pack 17 and Sentry-Bot, the tripod gun turret from Pack 2.
