2D gameFixed-screen space shooter arcade gameOriginal by Taito (Tomohiro Nishikado)
Space Invaders, one of the pioneers of the arcade shooter, has you blasting rows of descending aliens with a cannon at the bottom of the screen. Its tension comes from one simple rule: enemies speed up as their numbers fall, and the pressure multiplies as they near the ground. Shields that slowly erode force the player to balance attack and cover, while the mystery bonus ship crossing the top of the screen is a constant temptation for a risky shot.
For a similar game, wave pacing and bullet readability are the most critical issues: enemy formation, the acceleration curve, enemy fire rate and destructible shields all need careful tuning. A modern take usually adds power-ups, boss waves and permanent upgrades. The Space Invaders name and its iconic alien silhouettes are protected, so you need to keep the retro mood while building original enemy designs and a world of your own.
Why Space Invaders works: the core loop
Systems you need to build a game like Space Invaders
Formation and wave movement
A wave system where enemies shift sideways and drop down as a block, speeding up as their numbers shrink.
Destructible shields
Obstacles that erode pixel by pixel under both player and enemy fire, offering strategic cover.
Enemy fire and bullet management
A readable threat system that balances on-screen bullet count, fire rate and which enemies shoot.
Bonus ship and risk-reward
A target that passes at random intervals, awards big points when hit and lures the player into exposed positions.
Power-ups and boss waves
Short-lived powers such as double shot, shield and laser, plus large enemies that arrive at set intervals.
Score, combos and rankings
Score multipliers that reward hit streaks, with local and global leaderboards.

The hard parts of this genre
Tuning the pace
If enemy acceleration is too harsh players get overwhelmed, and if it is too gentle the tension disappears; the wave curve must be tuned through playtesting.
Modern player expectations
The pure classic rule can feel repetitive quickly today, so power-ups and progression must be added without breaking the balance.
Visual identity and copyright
The alien silhouettes and the name are protected, so while you use a retro pixel aesthetic the enemy and ship designs must be entirely original.
Team, timeline and budget
The estimate is based on the genre’s core systems, content volume, multiplayer and live-ops needs plus QA and project management: about 205 person-days for the full scope and 92 person-days for the first version. Cutting scope (fewer levels, one map, fewer characters) lowers the budget directly. Store accounts, servers, audio licences and user-acquisition budget are separate items. We send a fixed written price within 24 hours after the game design document.
Monetisation
Retro shooters like this rely on rewarded ads for continues or extra power-ups, ads between levels and a paid ad-free version. Ship skins, bullet effects and theme packs can be offered as cosmetics. If there is a permanent upgrade system, soft currency sales can also be added.

Choosing a game development company for a game like Space Invaders
Most people searching “make a game like space invaders” are really looking for a reliable game development company. When comparing quotes, check four things:
- Can you play their released 2D games on your own phone?
- Are the source code, art files and store accounts transferred to you by contract?
- Do they build a playable prototype first and show a demo every two weeks?
- Are ads, in-app purchases and analytics set up as part of the quote?
Copyright and originality
Game mechanics on their own are generally not protected, but names, logos, characters, art, audio and level designs are. That is why we build a game “like Space Invaders” with your own name, art and world. This is not legal advice; we recommend a trademark search before launch.
Frequently asked questions
How long does it take to make a game like Space Invaders?
A playable version with basic waves, shields and scoring can be ready quickly. Time grows as you add boss waves, permanent upgrades and LiveOps.
Will there be copyright issues?
The mechanic of shooting descending enemies is generally free to use, but the Space Invaders name, its iconic alien designs and sounds are protected. Treat the game as a nostalgic reference and create your own characters; this is not legal advice.
Which engine is suitable?
Unity 2D and Godot 4 suit mobile and PC, while Phaser is good for fast browser releases. For this game, a stable frame rate and responsive input matter more than the engine.
How do I modernise a classic shooter?
Adding roguelite upgrade choices, boss fights or short daily challenges works well. Keeping the familiar rule while adding a small layer of decisions to each session boosts replayability.
