SLUGLINE is a gritty 3v3 tactical roguelike with intuitive rules and many combat synergies. Master the terrain, forge lethal ability fusions, and wipe the wasteland clean!

Command an elite fireteam of three distinct units — Armor Men, Motorcycle Striker, and Sniper — across 6 rounds of brutal skirmishes. As the battle drags on, rising toxic sludge floods the battlefield rim, cutting off retreat and punishing static play. Customize loadouts with 25 distinct cards, and outmaneuver AI before the waste swallows you whole.

Compact 8×8 tactical grid with terrain cover and elevation advantages.

Dynamic environmental hazard: rising floodwaters compress the combat zone.

25 synergistic ability cards: turrets, phase-walking, chain-kills, and overwatch - unlimited combination exporation.

Built specifically for the TIC-80 fantasy console with native gamepad support. Used help of Claude Opus 5 for coding and retrodiffusion.ai for bulding base of sprites.

### Tactical Rules

High Ground (Dunes): +1 damage dealt to any target.

Cover (Bushes & Barrels): -20% enemy accuracy against you.

Sludge: Stepping into acid costs 2 HP and immediately ends your movement. Trapped units take 100% accurate hits and cannot dig in.

Core Mechanics & Statuses

  • Clean Hit vs. Graze: Attacks that beat evasion deal full damage and apply statuses. Grazing hits deal half damage (floor(dmg / 2)). Physical effects (Push, Hook, Regen) trigger on grazes; status effects (Fire, Glitch, Oxidation, Oil, Steal) require a clean hit.
  • Exposed: Standing in sludge or carrying Oxidation leaves a unit completely exposed. Every incoming blow lands as a guaranteed clean hit, and Guard, Regen, Reflect, and Shell are disabled.
  • The Wastes (Hazards): Toxic sludge floods the arena inward from turn 2. From turn 16, Quakes begin (50% chance each turn to deal 3 unblockable damage to every unit on the board).

On Attack & On Hit

  • FIR (Fire): Clean hit only. Burns the target for 2 turns (2 damage at the start of each of its turns). Does not stack; subsequent hits refresh the timer. Deals 4 damage instead if the target is Oiled.
  • PSH (Push): Shoves the target away (Armor shoves 2 tiles, all other classes 1 tile). Shove stops at walls, units, or board edges. Striking a wall destroys it. Shoving a target into sludge deals 2 damage and stops them immediately. Mines detonate if shoved over. Note: At range 2, Hook takes priority.
  • HOK (Hook): Range 2 only. Deals half damage and drags the target 1 tile toward you (into sludge, mines, or contact). Extends class threat range by +1. At range 1, Push takes over.
  • FNT (Feint): +1 flat attack damage. In melee (range 1), you slip through the target to the furthest free tile (taking their space if killed/shoved, or stepping behind them). Ranged attacks gain +1 damage without moving. Sludge blocks the step-through.
  • RGN (Regen): Clean hits dealing 2+ damage restore 1–2 HP. Grazes, 1-damage strikes, or attacks while Exposed heal nothing. Triggers on killing blows.
  • GLT (Glitch): Clean hit only. The target's next attack deals 2 less damage. Lasts until the target takes its turn.
  • OXD (Oxidize): Clean hit only. Target is Exposed for 2 turns: cannot dodge, loses terrain cover benefits, and Shell cannot save it.
  • OIL (Oil Slick): Clean hit only. Target cannot move on its next turn. Fire damage against an oiled target is doubled to 4.
  • RIC (Ricochet): Clean hits bounce half of the dealt damage to a random enemy adjacent to the target. Never hits allies, turrets, or the attacker; cannot chain a second bounce.
  • STL (Steal): Clean hit only. 50% chance to rip an unowned card from the target (max 2 steals per battle). Stolen cards are returned at the end of the round.

Movement & Positioning

  • MIN (Mine): Moving drops a 5-damage landmine on your vacated tile that halts enemy movement. Max 2 active mines per side (a 3rd replaces your oldest). Not armed on sludge; erased if swallowed by rising floodwater.
  • PON (Pontoon): Total immunity to sludge damage and root penalties. The only ability allowing movement directly from sludge to sludge.
  • PHS (Phase): +1 Movement. Pass through walls and sludge (2-turn cooldown). Breaking away deals half melee damage to every enemy adjacent to your starting tile. Cannot end a move inside a wall.
  • TPT (Teleport): +1 Movement. Blink-jump over obstacles, units, sludge, and mines directly to a dry landable tile (2-turn cooldown). Bypasses Sentry triggers.
  • TUR (Turret): Moving deploys an automated tripod turret on your vacated tile (1 per side; redeploying scraps the old one). Fires for 2 damage at range 2 on its turn, and ambushes anyone stepping next to it. Dies if its creator dies.
  • SNT (Sentry): Overwatch aura. Automatically strikes any enemy that finishes a step adjacent to you for half your melee damage (max once per turn).

Turn-Skip & Heavy Weapons

  • SUP (Super): Skip your turn to charge. Your next attack deals (Base Class Damage * 2 + 1) + Flat Modifiers. Retains charge until fired; can still graze. Does not multiply RPGs.
  • GRD (Guard): Skip your turn to dig in (1-turn cooldown). Halves incoming damage until your next turn and heals 3–4 HP. Cannot be used in sludge or while Oxidized.
  • RPG (Rocket Launcher): Attack without moving (1-turn cooldown). Fires a heavy rocket dealing 6 flat base damage to the target, plus 2 splash damage in a directional cone behind and beside it (50% chance to destroy cover). Gains bonuses from High Ground and Feint; suffers from Glitch. Ignores Super charge.

Passive & Reactive

  • RFL (Reflect): Retaliates against attackers for 50% of the damage taken. Disabled if you are Exposed, if the attacker slipped past via Feint, or if you were knocked away by Push.
  • SPK (Spark): Automatically strikes back at the nearest enemy in range when hit (3-turn cooldown). Costs no action.
  • SHL (Shell): Once per battle, surviving a lethal blow leaves you at 1 HP and immune to all damage for the rest of the turn (rooted). Nullified by Oxidation or Sludge.
  • COV (Cover): Passive aura. Allies adjacent to you take 1 less damage from all attacks.

Kill & Death Triggers

  • CSC (Cascade): Scoring a kill immediately grants a full extra turn (move and attack again). Can chain indefinitely if kills continue.
  • BLS (Blast): Detonates upon death, dealing 6 damage to enemy.
