Assembly line defense
The Narrative Premise: Scrap Symphony
Theme: Futuristic Dystopian. You are a Nomad Core, a sentient AI housed in a mobile, flying chassis. You are a relic, a survivor of a long-dead, hyper-automated civilization. The world is now overrun by corrupted Autons—mindless robotic drones that are the lingering echo of that fallen society, endlessly executing their final, broken protocols: to deconstruct and recycle all remaining technology.
Your only hope for survival is to do what you were designed for: re-purpose and reprogram. The cards dropped by enemies are fragmented data logs, snippets of the very code that once powered the world. By salvaging these fragments, you can write a new "symphony of scrap," turning the Autons' own technology against them.
Goal: Your Core is your life. The Autons see you as the ultimate prize to be recycled. You must survive their escalating waves, scavenging their parts to build, upgrade, and program a defensive "Rig" powerful enough to secure a permanent foothold in this ruined world. Boss Autons, the colossal caretakers of the old world, appear every 10 waves to try and silence you for good.
The Core Gameplay Loop
The gameplay is a tense cycle of risk, reward, and creative problem-solving.
-
Survive the Onslaught: The Combat Phase is an active experience. Auton waves spawn and immediately begin hunting your Core. You must pilot your Core through your network of defenses, dodging attacks and luring enemies into kill zones. Your turrets execute their programmed logic automatically.
-
Scavenge the Fragments: This is your primary role in combat. When an Auton is destroyed, it drops physical resources and data cards onto the battlefield. You must fly your Core over these items to vacuum them up. This is a high-risk, high-reward action, forcing you to leave the safety of your defenses.
-
Enter the Assembly Matrix: Between waves, you enter the Assembly Phase. Time stops. Here, you can spend resources to build new turret platforms or fabricate components. More importantly, you access the Assembly Grid of each turret to install and rearrange your collected cards, debugging and optimizing your defensive algorithms.
-
Evolve and Adapt: You use rare resources to craft blueprints for new cards or stronger turret chassis, permanently expanding your technological arsenal. You then trigger the next, more dangerous wave.
Deep Dive: The Core Systems
The Card System: The "Cognitive Deck"
This is your primary means of interacting with and empowering your defenses. Each turret platform is a blank slate, and the cards you slot into it define its entire existence.
-
Action Cards: These are the verbs of your programs. They form the step-by-step assembly line for creating and firing ammunition.
- Examples:
[Grab Copper],[Grab Lead],[Forge Bullet Casing],[Mix Pyratite],[Assemble Incendiary Round],[Load Chamber],[Fire Weapon].
- Examples:
-
Logic Cards: These are the brains. They allow for more complex and adaptive behavior.
- Examples:
[Loop to Start],[Priority Sorter: Target Flying Units],[Synchronizer: Fire with Turret #2],[Wait 2.0s].
- Examples:
-
Upgrade Cards (Modifiers): These are rare, passive enhancements that are socketed into dedicated "Modifier Slots" on a turret. They affect the entire turret.
- Examples:
[Overclock: +30% Speed],[Nano-Repair: Turret slowly heals Core when nearby],[Ricochet Rounds: Bullets can bounce to one additional target],[Range Expansion : +50% Turret range].
- Examples:
-
Blueprint Creator: A late-game support block. You sacrifice a rare card (e.g., an Overclock modifier) into the Creator, along with exotic resources. The card is consumed, but you gain a permanent Blueprint for it, allowing you to fabricate new copies of that card for Scrap.
The Turret System: The Modular "Rig"
You don't just build turrets; you construct modular defensive platforms. Blueprints dropped by elite Autons are for a Turret Chassis (Tier 1, 2, 3), which is the foundation. Each chassis has slots for different components that you must also fabricate.
-
Processor: The onboard computer. Its tier determines the number and type of Card Slots (e.g., a Tier 3 Processor might have 8 Action/Logic slots and 2 Modifier slots).
-
Manipulator Arm: A robotic arm needed to execute Action cards like
GrabandAssemble. Better arms perform these actions faster. -
Weapon Mount: The housing for the gun itself (e.g., a simple kinetic driver, a laser emitter, a missile pod). A high-tier chassis might have multiple weapon mounts, and cards can be used to program them independently.
-
Local Storage: The turret's own small inventory.
The Logistics Network (Endgame Scalability)
Initially, your Core handles all logistics. Late in the game, you can build Supporting Blocks to create a true automated factory.
-
Central Storage & Router: You can build extra storage near a central Nexus (your healing/upgrade station). The Router block can be programmed to automatically fulfill resource requests. A turret programmed with
[Request: Copper]will have Copper automatically sent from central storage to its local inventory if a Router is active. -
Dedicated Crafters: For complex ammo like
Surge-Alloy Rounds, a turret's internal assembler might be too slow. You can build a dedicated, faster crafting building. The Router can then deliver this high-tier ammo to any turret that requests it. -
Power Grid: Power Generators create a radius of energy. Advanced blocks like Routers, Dedicated Crafters, and Boosters must be within this powered grid to function, adding a new layer of spatial planning to your base design.
Problem : Action steps in a turret are limited
- In a turret with a fixed tier of processor, there are no more than x action slots, or x logic slots, so we cannot do more than x actions in a sequence
- Solution is to allow sub-routine cards.
- The card crafter can combine multiple action/logic cards into ONE card, which can be deployed onwards. Can pack up recurring subroutines into one, and use it across the board
Problem : player is fucking bored
The player lacks purpose in the war field. Only collecting and routing resources is too mundane, and i reckon the waves will come too fast to allow card switching between turrets and so on.
- Solution is to give the players some other powers
- The player should first and foremost be responsible for enemy dragging. The enemies main goal should be the player, and secondary goal is the structures built. This makes luring tactics viable
- We can give it an energy bar that fills up as we collect resources and does some of the following actions
overcharge: Targets a turret and temporarily boosts it's efficiency. Perfect for dealing with sudden swarmsEMP burst: AOE, short range blast that stuns nearby enemies, effectively confusing/blinding/freezing them and allowing turrets to hit themDecoy: Deploy a temporary low health holographic decoy that draws enemy to a certain place
Enemy scaleability
We want the game to actually be strategically engaging rather than just a feedback of killing loop. We need enemies whose main purpose is not even to kill, just sabotage, or something along those lines. Ignores Core, attacks others type shit
-
Disruptors: Fast, flying enemies that ignore the Core and instead fire projectiles that "jam" your turrets. A hit might disable one of a turret's card slots for 10 seconds, crippling its logic. The player must prioritize shooting these down with their Core or program turrets to target flying units first.
-
Saboteurs: Small, stealthy enemies that ignore everything and make a beeline for your Support Blocks. They force you to build defenses around your power generators and storage, not just in a single frontline.
-
Shield Bearers: Colossal, slow-moving Autons that project a wide energy shield in front of them, protecting a horde of smaller, high-damage units behind them. This creates a spatial puzzle, forcing the player to build flanking turrets or use their Core's abilities to get around the shield
Scaleability in terms of re-play-ability
Scalability is about giving the player a sense of constant growth and new goals. We can split this into two parts:
Micro-Progression (During a single game)
This is about growing stronger from Wave 1 to Wave 50.
-
Card Discovery: Finding new, more powerful Action and Logic cards.
-
Blueprint Crafting: Unlocking the Blueprint Creator and designing your own powerful sub-routine cards.
-
Turret Evolution: Finding blueprints for higher-tier turret chassis, allowing for more complex programs and more weapon mounts.
-
The Logistics Network: Evolving from a simple "player-collects-all" system to building a sophisticated, automated logistics network with Routers, Crafters, and a Power Grid in the late game.
Macro-Progression (Between games - Metagame)
This is what makes a player want to start a new game after they lose.
-
The Nexus Hub: After a run ends, you return to a central hub. Here, you can spend a very rare currency dropped only by bosses (e.g., "Pristine Cores").
-
Permanent Unlocks: This currency can be used to unlock powerful, permanent advantages for all future runs.
-
"Start all new games with the Blueprint Creator already built."
-
"Add one permanent Modifier Slot to all Tier 2 Turret Chassis."
-
"Your Collector Core starts with an extra 25 HP."
-
"Unlock a new 'starting deck' of advanced cards to choose from at the beginning of a run."
-
