No one else is left.

Your entire civilization has been wiped out by an unstoppable space fleet controlled by the AI super-entity known as V.E.G.A.

You are the last remaining S-Class pilot of a secretive space defense program know as Alpha Mono. Your ship is a living weapon, able to adapt to this dangerous situation and take on V.E.G.A. as you make your escape.

But even if you somehow manage to outrun the overwhelming enemy forces... greater dangers lie beyond your planetary system.

How long can you survive?



Retro Shoot 'em Up with a Modern Twist

ALPHA MONO S is a time-based survival shmuplike inspired by classic arcade style STGs from the early 90's and modern roguelites like Vampire Survivors. Shoot and dodge your way through 10 action-packed minutes of unique enemies and bullet chaos while powering up your ship to overcome challenging hurdles and attempt to complete your mission.

In Alpha Mono S, you will...

  • Survive increasingly difficult waves of enemies and minibosses
  • Earn XP to level up and access cool new weapons and abilities
  • Purchase powerful S-GEAR upgrades with in-game credits
  • Mine asteroids to collect valuable crafting materials
  • Enhance your ship with rare power-ups
  • Unlock mysterious new technologies by completing your mission

Alpha Mono S Strategy Guide

THIS SECTION MAY CONTAIN SPOILERS. Here are a few tips and some information to help you get started and learn about the world of Alpha Mono S.

This game has simple mechanics but it takes quite a bit of concentration, fast reflexes, and hand-eye coordination to "win". You only have to control your ship's position while your systems automatically fire or trigger their effects.

Enemies in Alpha Mono S swarm your ship and use whatever weapons they have at their disposal in attempt to obliterate you. Spatial awareness is key so keep on eye on enemy positions and the trajectory of their weapons to stay alive or you may end up space dust.

You will encounter multiple minibosses throughout your mission. Unlike normal enemies, they do not drift off the map and will continue to pursue your ship until they succeed or are destroyed. Minibosses are much more difficult to take down and are rumored to carry an unknown power source. More data is needed.


You can level up your ship by collecting XP loot from enemies to add new systems and increase their power. Having these abilities will drastically increase your chances of survival.

Mining & Materials

In order to mine asteroids for materials, you'll first need to obtain the Drill upgrade when leveling up. There's a chance it will pop up every time you level up. When activated, your trusty Drill bot will begin following your ship around. If you are within range of an asteroid, the Drill will automatically mine the asteroid until it breaks to reveal materials.

Gather materials to purchase higher level (3+) S-GEAR from the shop. You can increase your cargo size with the Cargo upgrade so you can carry even more. The normal max is a 25 material limit per mission without a Cargo upgrade.


  1. Watch out for opportunities to damage minibosses while moving around
  2. Choose damaging upgrades to gain an early advantage
  3. Focus on enemies you can destroy in one hit to maximize XP
  4. You will need to slow down fast-moving asteroids to mine them
  5. Zippers have a chance to drop really rare items

Leaning a bit towards bullet hell than arena survival.  The meta upgrades might help, but the teeny tiny benefit for how long I had to scrap for them turned me off.  Hard's fine, but you may want to tune this just a bit towards casual for this genre.

Thank you for sharing your feedback. I will take this into consideration as I continue to tweak the gameplay for future updates.

From your experience, would you prefer larger stat bonuses from S-Gear or a lower material cost (asteroid material) to purchase the meta upgrades?

Very polished and fun. So cool :)

Thanks Danie!
