Hold & Advance

Descend deeper into an underground world, discover abandoned alien stations and use them to craft powerful upgrades. Every time you start a station, it attracts enemy waves, so going in unprepared is almost a guaranteed failure – turrets, drones, mines and traps become your main weapons and tools for controlling the battlefield.

The world is split into several zones, from the relatively safe surface to the dangerous core deep below. Each zone has its own visuals, enemies and resources. New abilities gained at the stations - like double jump, jetpack or mini‑map – do not just make your character stronger, they unlock previously inaccessible areas and completely change how you move and explore.
Key Features
Hand‑crafted underground world that gradually opens up as you grow stronger

Tactical defense of alien stations using turrets, drones, mines and traps

Modular turret system: sockets and modules let you customize attack types, behavior and synergies for each threat

Radical upgrades that change your playstyle: go from cautious exploration and manual gathering to free flight, full map awareness and near‑total control over the environment

Tactics over reflexes: success depends on preparation, positioning, defense setup and resource management rather than perfect aim

"Risk for reward" day–night system: at night enemies are tougher and more frequent, but resources are far more abundant

Defend Stations, Earn Radical Upgrades
All key upgrades are crafted exclusively at alien stations. Starting a crafting process takes real time and triggers an enemy wave that will focus on destroying your station and defenses. Prepare the area beforehand: place turrets, lay mines, and pick the right weapons. Every successful defense unlocks new abilities, weapons and tools that noticeably change your experience and open the next step in your progression.
Grow Stronger, Play Differently
Progression is built around new capabilities, not just bigger numbers. Early on you manually gather resources, carefully sneak through caves and barely survive the first waves. By the end you move freely around the world, see the map and resource locations, experiment with complex module setups and confidently handle the toughest defense scenarios.
Tactics Matter More Than Reflexes
Victory depends on how you prepare for incoming threats. Choose which weapons to bring, where to build sockets, which modules to combine and how to split resources between scouting and fortifying your position. Failure is not a disaster: if a defense attempt goes wrong, you get your resources back, the station only needs minor repairs, and you can quickly try a different strategy without sinking into exhausting grind.
Risk for Reward
The day–night cycle adds an extra tactical layer. Daytime is safer and more comfortable for exploration; at night enemies become tougher and more numerous, but resource gains grow as well. Whether you keep pushing forward in the dark or wait for sunrise is entirely your call, depending on your goals and your appetite for risk.
