About
Awaken from a century of cryosleep to find yourself the sole human survivor on a barren world overrun by aggressive flora. Calyx is a tense RTS base-builder where you must establish a mining foothold, manage volatile power grids, and push back against an ever-evolving plant-alien superorganism.
Story
You are the last remnant of an Avaris Corporation mining expedition, guided only by a glitchy, out-of-date ship AI. As you drill for resources, the planetary surface fights back—the Calyx, a hive-mind vegetation, spreads relentlessly to reclaim the land, forcing a desperate battle for survival and extraction.
Gameplay
A blend of classic RTS base construction and survival defense. Players must expand their territory using a network of power pylons, manage ore extraction that physically eats away the terrain, and command mobile units like Tanks and Scouts. The pacing shifts between strategic logistical planning (using the active pause) and frantic combat against swarms of mutating vines and roots.
Key Features
- 1**Hub-Centric Infrastructure**: Build outwards from a central Hub; if it falls, the mission is over.
- 2**Volatile Power Grid**: Manage energy distribution via pylons; losing power disables defenses instantly.
- 3**Terrain Deformation**: Ore mines consume the ground beneath them, requiring constant expansion.
- 4**Evolving Threat**: The Calyx adapts, spreading 'evil plant slime' and mutating from vines to massive roots.
- 5**Tactical Pause**: Hit Spacebar to freeze time, plan layouts, and queue orders amidst chaos.
- 6**Tech Progression**: Unlock heavy weaponry, advanced logistics, and improved mining yields.
