About this game

Overspace — a fast-paced top-down shooter RPG where only the strongest heroes survive.

Endless waves of aliens and undead are coming — humanity’s last line of defense is you.
This is a space shooter and action RPG in one: every second counts, and only sharp reflexes, accuracy, and strategy will keep you alive.

Fight through survival arenas, upgrade your heroes, improve weapons and armor, enhance combat drones, and turn your soldier into the ultimate war machine.
Each battle tests your skill; each encounter brings you closer to saving the galaxy.
Overspace combines the intensity of a top-down shooter with the depth of an RPG, creating a tense sci-fi survival world where victory belongs to those who shoot first.

KEY FEATURES

• Fast-paced top-down action shooter with RPG elements.
• Survival arenas filled with alien and undead hordes.
• Deep hero progression system — upgrade gear, drones, and skills.
• Offline gameplay — play anytime, anywhere.
• Boss fights and thousands of enemies on every map.
• Powerful upgrades, drones, and unique sci-fi weapons.
• Vivid graphics and atmospheric space environments.


HERO UPGRADES

Collect crystals and resources during battles to strengthen your fighter.
Increase damage, armor, and movement speed, upgrade support drones, and unlock new abilities.
The RPG progression system lets you build your own playstyle — from agile assault to heavy defense.
Smart upgrades and weapon choices are the key to survival in the toughest fights.


ALIEN INVASION

The crew of starship 117 vanished deep in space. You’re the last surviving Spartan, trapped in endless arena battles against alien swarms.
The invasion spreads across galaxies, and only you can stop it.
Every mission is a fight for life — as alien hordes grow stronger, the action becomes even more intense.


POWERFUL ARSENAL

Unlock and upgrade dozens of weapons — from basic blasters to a black-hole cannon.
Wield gravitational saws, plasma lasers, pulse grenades, and more.
Combine damage types and weapon effects to destroy enemy formations and crush heavily armored bosses.
Each upgrade makes your shooter RPG experience more explosive and satisfying.


SIMPLE, INTUITIVE GAMEPLAY

One-hand controls and auto-shooting let you focus on pure action.
Smooth top-down controls provide full battlefield awareness, while every move and dodge matters.
Jump in for quick runs or dive into long survival sessions — the action never stops.


WORLD AND ENEMIES

Explore diverse sci-fi arenas — ruined colonies, asteroid fields, and infected stations.
Face alien predators, mutants, and mechanical horrors — each with unique attack patterns and weaknesses.
Adapt, plan, and master your tactics to survive the onslaught and unlock rare gear.


BOSSES & SURVIVAL

Epic boss encounters push your reflexes to the limit.
Their multi-phase attacks require precision and well-chosen gear.
Only a fully upgraded hero and a tactical loadout can withstand the assault.
You are the last defender of humanity in this space shooter RPG — every second determines the fate of the mission.


PREPARE FOR BATTLE

Overspace is a blend of shooter, action RPG, and survival — fast, challenging, and endlessly replayable.
Use your weapons, drones, and upgrades to hold the line against the alien invasion.
Fight, upgrade, and survive — prove that humanity’s last hope is still alive.
Shoot first… or be forgotten among the stars.

I spent 6K gems on golden packs, but it did not give me any new characters. Also, I cleared stage 6, but the game asks me to kill boss 5-3, which I have killed more than 100 times. However, the game gets stuck there and doesn't count any of them/also I can't travel between the planets, now I'm at stage 1 and can't do anything about it/ and you can't SAVE the game progress

kinda fun, but only 5 levels? nothing left to do, so nothing to spend money on. Will give a week or so for more levels then uninstalling. probably one of thoes quick money games where they lure you in, get you to spend then just don't develop it, and if that's the case, I'll be getting a refund and reporting as a dead game.

Good game. Good control with the exception of one change I would like to see. The side bar options on the left while you play can interfere with game play, specifically the directional pad. Fun game though. Im even willing to spend real money.
