About this game

Description

Supplied by the Steam store

MORTISCRIPT: Undead Auto Battler is a dark fantasy strategy RPG about programming an undead army and watching your plans play out on the battlefield.

You are a Vampire Queen who has returned after being betrayed and left for dead. Your manor lies in ruins, your kingdom is in enemy hands, and rebuilding your power means putting the dead back to work.

Write the Orders

Before battle, give each formation a set of simple rules built around WHEN → ACTION → TARGET .

Your units fight on their own, but the decisions they make come from the Orders you wrote. No programming knowledge is required.

Watch Your Plan Play Out

Once the battle starts, control gives way to observation.

Build formations around each other, watch their Orders interact, and see exactly why a plan worked — or why it fell apart. Then change the rules and try again.

Prepare for the Expedition

Choose which forces to send, check the expected opposition and make sure their Orders are ready before leaving the manor.

Expeditions contain multiple encounters and health carries between battles, so knowing when to push forward and when to retreat matters.

Reclaim the Kingdom

Return to your manor between expeditions to unlock new undead formations and expand what your army can do.

Then push outward through hostile regions, dungeons and bosses as the Vampire Queen takes back the kingdom that betrayed her. Each region introduces new enemies and problems for your Orders to solve.

Featuring

Rule-based combat built around WHEN → ACTION → TARGET

Auto-battles driven by the Orders you write

Undead formations with distinct mechanics and synergies

A combat view that explains why your units acted

Multi-encounter expeditions with persistent health

Manor progression and permanent formation upgrades

Handcrafted regions, dungeons and bosses

No programming knowledge required
