All Upgrades in Alien Invasion: RPG Idle Space
There are multiple different types of upgrades, each offering unique advantages. The best part of the game is that players can choose from a wide variety of upgrades without being limited to just a few options. In essence, you will be able to upgrade every aspect of your alien. The real strategic choices come during the early game when resources are scarce and you need to prioritize which enhancements to pursue first. Don’t worry; we have covered all the upgrades along with explanations for what each one does. Here is the breakdown:
Catching Speed – This upgrade allows your alien to hunt humans faster. Whenever you catch a human, you will see a small timer circle next to them, indicating how long it takes to capture any given person. Depending on the type of human, this timing can vary. Enhancing this upgrade allows you to catch more humans in less time.Cargo Capacity – As the name suggests, this upgrade is directly linked to how many humans you can carry at any given moment. The higher your cargo capacity, the more humans you can hunt before needing to return. This is an important early-game upgrade as it allows you to gather resources without constantly visiting the cargo base.Move Speed – Enhancing this upgrade directly increases the movement speed of your alien. Note that this refers to actual travel speed and should not be confused with catching speed. Players can enhance this aspect to move faster between zones, which also helps in unloading cargo more quickly.Catching Tentacles – This upgrade allows players to catch multiple humans at once by adding another tentacle. Your alien uses its tentacles to capture and drain humans; adding an extra tentacle helps you load meat and bones faster.Catching Radius – The catching radius determines the area around your alien where enemies can be captured. This is indicated by a small white circle near your character; if an enemy moves outside this zone, they will not be caught. Enhancing this radius is a good choice for players who prefer not to constantly chase their targets.
