To make a game like Vampire Survivors with AI, describe a compact arena, automatic attacks, incoming enemy formations, and upgrades that reshape each run. Chatforce turns your description into a browser-playable game, then you can tune movement, attack timing, and upgrade choices by chatting with the AI team.
Start with pressure you can read
A horde survivor run is a movement problem wrapped around automatic offense. Your character attacks without a button press, so the player spends attention on spacing, enemy approach, and collecting experience while staying out of corners. The excitement comes from a screen that grows busier in measured stages. Early foes teach the danger zones; later groups make the player combine a weapon's reach with a safe route through the crowd. Arcade games use the same movement-first challenge.
| Design choice | What to decide |
|---|---|
| View | Use a readable 2D overhead arena with space to kite around threats. |
| Attack rhythm | Choose automatic weapon timing and how attacks aim or travel. |
| Run length | Set a survival target and milestones for escalating danger. |
| Level-ups | Offer a small set of upgrades with distinct tactical effects. |
| Reward | Decide what a successful run unlocks in the next attempt. |
Make each choice change the route
Level-up choices should affect what the player does in the next minute. A piercing shot can reward lining up a row of enemies, while a short-range burst asks the player to approach danger. A movement boost can make experience pickups reachable, but it does not solve a weak attack by itself. Give options different jobs, then let a few combinations support a recognizable plan. If every upgrade only increases damage, the decision becomes arithmetic instead of strategy. Roguelike runs use the same level-up choices to vary each attempt.
Shape a run that keeps its pressure fair
Choose the arena view
For this design, start in 2D: an overhead arena makes enemy distance and escape lanes easy to read, and Chatforce provides a horde survivor scaffold. Chatforce's 2D or 3D choice is made when the game is created and cannot be changed later, so decide before describing the build. Specify whether the arena is a single bounded space or a scrolling field, how the player moves, and what blocks movement. If you choose 3D, describe the world and directable camera clearly, since depth can hide threats.
Define automatic offense
Write down how the first weapon behaves when the player does nothing: its cooldown, target rule, travel speed, range, and what happens when it hits. A simple bolt that seeks the nearest foe teaches the attack loop, while a forward sweep rewards aiming through a cluster. Ask for a visible windup or clear effect so players can tell when damage lands. Keep the first weapon dependable, then add upgrades that alter a single property at a time. This makes it possible to notice whether an upgrade improves decisions or only adds screen noise.
Plan enemy and reward cadence
Describe waves as changes in behavior, not just larger health totals. A slow pack can push the player from behind; a quick, fragile enemy can threaten an exposed lane; a durable foe can force a detour. Set intervals for experience drops and level-up screens, then say whether the world pauses while a choice is open. Each choice should use plain language and show its effect. Offer three options with different uses, such as widening a sweep, adding a second bolt, or collecting nearby experience, so the player has a real tradeoff.
Create a run endpoint
Give the run an understandable finish, such as surviving a final wave or defeating a distinct enemy after a timer. Decide what happens when health reaches zero and what information the end screen reports: elapsed time, foes escaped, and the upgrades assembled are useful clues for another attempt. A brief between-run reward can unlock a new starting tool, but avoid making early attempts feel pointless. Ask the AI team to build a playable first version, then report specific issues after trying it, such as a crowded corner or a level-up that arrives too late.
Example prompt: Make an original 2D horde survivor game about a clockwork gardener defending a moonlit greenhouse from animated seed pods. The character moves with directional controls and automatically fires a slow pollen ring at nearby threats. Enemies arrive in readable waves, and defeated foes leave glowing dew that grants experience. At each level, pause play and offer three upgrades that change range, orbit count, or movement speed. Build a short run with a final glasswing beetle, clear hit feedback, and original botanical art, names, music, and story.
Tune the crowd, then tune the build
Test whether the player can identify a safe direction while attacks are firing. If the arena becomes a wall of effects, ask for fewer simultaneous particles or stronger contrast between enemies and the floor. If movement feels unimportant, reduce automatic targeting precision or add foes that approach from different angles. Then replay with different upgrades: a useful pick should invite a change in route or target priority. Chatforce typically produces a first playable in 10 to 15 minutes. Iterate by describing what felt off, requesting one change, and replaying to see its effect. If survival runs are your focus, the survival game maker also supports an original survival concept. Distinct pixel art for each enemy keeps a crowded arena readable.
Publish a run friends can compare
When the arena, choices, and ending feel coherent, publish the game to get a shareable browser URL. Friends can play without an account, which makes a short survival challenge easy to pass around. If you want a shared run, Chatforce supports online multiplayer in 2D with up to 8 players per room; describe whether players revive one another, share experience, or compete for drops. The creator owns the work, and published games have no watermark. Keep the premise and every asset original before you share it. If you are comparing AI tools, Chatforce vs Rosebud is one comparison.
Frequently asked questions
Can I make a direct copy of Vampire Survivors?
Use it as a reference for broad horde survivor ideas such as automatic attacks and escalating waves. Make an original game with your own names, characters, art, music, and story, and do not reproduce its specific assets or presentation.
Does Chatforce have a horde survivor starting point?
Yes. The 2D genre scaffolds include horde survivor. Describe the weapons, enemies, upgrade choices, and run structure you want, because those details make your particular game distinctive.
Can friends join a run?
Chatforce supports online multiplayer in 2D and 3D for up to 8 players per room. Explain how cooperation should work, including whether players share rewards or help each other recover.
