2D gameHand-animated run and gun action gameOriginal by SNK
Metal Slug is a run and gun classic that stands out for extremely detailed pixel animation, comical soldiers and gigantic boss fights. Its most memorable trait is the generous animation craft that makes every explosion, enemy and scene feel hand-animated. Rideable tanks and vehicles, rewards from rescued prisoners and screen-filling chaos give the player a constant feast, and the humour amid heavy action defines the game's personality.
For a similar game, most of the budget goes into high-frame-count pixel animation and hand-crafted level design. On the technical side you need multi-directional fire, melee, grenades, a rideable vehicle system, destructible scenery and phased boss fights. Two-player co-op is essential to the genre. The Metal Slug name, characters and vehicle designs are protected, so recreate this nostalgic aesthetic with your own soldiers, humour and universe.
Why Metal Slug works: the core loop
Systems you need to build a game like Metal Slug
Frame-by-frame pixel animation pipeline
A production process where character, enemy and explosion animations are drawn with many frames and imported into the engine efficiently.
Weapons, grenades and melee
Limited-ammo weapons such as a heavy machine gun or flamethrower, grenades and an automatic knife attack at close range.
Rideable vehicle system
Vehicles such as tanks, mechs or camels with their own movement and weapon rules that can be abandoned when damaged.
Prisoner rescue and rewards
A system that rewards exploration, where freed prisoners drop weapons, points or bonuses.
Destructible scenery
An environment system where buildings, bridges and vehicles break apart and the scene reacts to the action.
Phased boss fights
Screen-filling enemies that change form as they take damage, with patterns you learn.

The hard parts of this genre
Animation cost
The frame-by-frame pixel animation that defines this genre is very labour-intensive; without planned art direction and a production pipeline, the budget gets out of hand.
Screen chaos and readability
Lots of explosions and enemies can make dangerous bullets hard to see, so a colour and effects hierarchy is needed.
Copyright and original humour
The Metal Slug name, characters and vehicle designs are protected; the comical military aesthetic must be built with your own character and world design.
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 390 person-days for the full scope and 176 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
For this genre, a premium release on PC and console is the best fit, and DLC packs with extra stages, characters and modes extend its life. On mobile, free introductory stages with a full game unlock, or sales of cosmetic character and weapon skins, are preferable. An aggressive ad model generally annoys this genre's audience.

Choosing a game development company for a game like Metal Slug
Most people searching “make a game like metal slug” 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 multiplayer servers, anti-cheat and scaling costs written into 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 Metal Slug” 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 Metal Slug?
Controls and a single stage can be prototyped quickly, but high-quality pixel animation and hand-made stages mean the full game needs a long production cycle. Art production is the biggest factor in the timeline.
Will there be copyright issues?
Run and gun mechanics and the rideable vehicle idea are generally free to use, but the Metal Slug name, characters, vehicle designs, sprites and music are protected. Use this nostalgic game as inspiration and create your own characters; this is not legal advice.
What kind of team does pixel art need?
An experienced pixel artist and animator directly determine the quality of the game. If art direction is set up front with a clear style guide, you get consistent results across different artists.
Which platform should I start with?
PC (Steam) is a good starting point thanks to controller support and a premium buying culture. If it succeeds, porting to console and mobile can follow with lower risk.
