Inside Earthsiege

The engine, piece by piece.

Six illustrated articles on how Dynamix's walking machines draw, fight and find their way through a campaign, and how we checked the reconstruction against the original.

Graphics engine

How Earthsiege draws a frame

Follow a HERC through fixed-point transforms, palette shading, polygon sorting and four planes of VGA memory.

Damage & physics

Taking a HERC apart

Armour, internal components, missing limbs and the machinery that turns a wreck into salvage.

AI & squad behaviour

How the HERCs choose a fight

What a machine knows about its enemies, how it chooses a target and weapon, and when it decides to withdraw.

Missions & campaigns

Building a battlefield

Follow authored mission data through random choices, campaign history, activation triggers and the return to the hangar.

Reverse engineering

Checking a reconstruction against the original

Controlled experiments, recorded missions and the few wrong pixels that led into the original memory allocator.

Music & sound drivers

Inside Earthsiege’s soundtrack

Hear the FM arrangements and sampled drums, follow a combat music change, and investigate the missing MT-32 melody.
