In Alien Invasion: RPG Idle Space, your journey as a ruthless, ever-evolving alien relies heavily on one crucial element: upgrades. As you consume humans and gather biomass, you unlock a comprehensive upgrade system that transforms your basic alien into a formidable apex predator. Whether you aim to extend your attack range, accelerate your devouring speed, or unlock terrifying new mutations, upgrades are the central force behind your alien's domination over humanity. This guide introduces new players to each upgrade and explains how they enhance your gameplay.

Understanding Upgrades in Alien Invasion: RPG Idle Space

In Alien Invasion, you play as an alien that drains life from humans to expand its biomass. Devouring humans rewards you with meat and bones, two distinct currencies used extensively to upgrade and mutate your alien into new forms with unique abilities. These upgrades are accessible via the purple tentacle icon in the bottom-right corner of the screen. Tap this icon to open the upgrades menu.

Inside, you'll find various abilities and power-ups. You can also boost your alien's base stats to improve survivability against hostile humans. Pursuing upgrades is a core objective for every player in Alien Invasion: RPG Idle Space.

Complete List of Upgrades in Alien Invasion: RPG Idle Space

The game offers a wide range of upgrades, each with unique advantages. A key feature is the freedom to choose from many options without being limited to just a few. Essentially, you can enhance every aspect of your alien. The real challenge arises early on when resources are scarce, forcing you to prioritize certain upgrades. To help, we've detailed every upgrade below, including their functions:

Catching Speed – This upgrade boosts your alien's human-hunting speed. When targeting a human, a timer circle indicates the capture duration, which varies by human type. Improving this stat lets you capture humans more quickly.Cargo Capacity – As the name implies, this upgrade determines how many humans you can capture simultaneously. A higher cargo capacity means more targets can be hunted before needing to return to the cargo base to unload. This is especially useful early on.Move Speed – This upgrade increases your alien's movement speed, helping it travel faster between areas. Note that this affects travel speed, not capture speed. It also speeds up cargo unloading.Catching Tentacles – Adding an extra tentacle enables your alien to capture multiple humans at once. Since tentacles are used to catch and drain humans, more tentacles mean faster collection of meat and bones.Catching Radius – This stat defines the area within which your alien can catch enemies, marked by a white circle around it. If an enemy exits this zone, they escape. Expanding the radius is ideal for players who prefer not to constantly chase down targets.
