Progress Report #4
Progress Report #3
In Stack Gun Heroes you defend a portal against hordes of infected robots trying to get off world. You'll design guns, slide up walls, level up your superpower, and earn the love of countless adoring fans in a universe teeming with robotic life.

Key features:
  • 1-4 player co-op FPS.
  • Gun improvisation.
  • Millions of superpowers.
  • Survive waves of enemies for credits. Invest credits into new mods and powers.
  • Skillful walljumping and wallsliding.
  • Online co-op, offline single player.
  • The STACKgen AI designs the game as you go.
  • No max difficulty.

Stackable Guns:
You can stack mods on your gun to change the bullets it shoots.

Stacking is deep. Combine any mods you want for unique effects.

E.G. Orbital Strike + Turret calls down turrets from orbit.

It even lets you stack dozens of mods at once to make an unbelievably awesome superweapon.

Randomly Generated Superpowers:
Ultranox trades superpowers from his humble shop.

Some powers I have seen:
  • The power to swing from walls and ceilings with stretchy ropes.
  • Every few seconds, slightly boost your speed. The boosts add up. Keep it going long enough and you run like superman.
  • Summon a tiny ball. A giant robot friend rampages for as long as you can keep the ball alive.
  • My friend found a power that let him call a HUGE bomb from the sun, obliterating everything. (and sometimes himself)

Every day his selection changes. You will never see the exact same power twice.

Your power lets you contribute to your team in a way that no one else in the world can. Choose your power carefully, because you can only wield one.

World Building with STACKgen
Everything you see in Stack Gun Heroes is designed on the fly by STACKgen, an advanced procedural generation AI. STACKgen understands design principles like game balance and pacing, and it uses complicated math to ensure your mods, powers, and enemies are both varied and balanced.

Like in Star Trek, each alien race has it's own technology and visual style.

STACKgen designed buildings on planet Uc with complicated pathways and one open side. They use a complementary colorscheme of teal and orange.

Adsprisplain architecture has a radically different look:

You can stack with this in mind. Would an orbital strike gun work well on Adsprisplai because they don't use pesky ceilings? It's up to you to see what works.

You'll have to deal with the unique weapons and fighting styles STACKgen designs for each enemy. For example, some enemies have directional shields, some can fly, and all of them have uniquely stacked guns.

From left to right, a level 3, 10, and 20 enemy.

As you progress, these enemies get more and more difficult. The game never runs out of ways to make enemies harder, so you can always find a challenge. I cannot predict how far players will be able to get using their creativity, Stack Gun, and superpower.

Releasing this game is the only way to find out.

Thank you for reading!

Ok, just got the coming soon page up:

There are a few new screenshots and a video that might be worth checking out for people who are curious what the current state of the game looks like.

super excited :D

It's definitely coming. I actually just submitted a coming soon page to Valve for approval yesterday. I think I'll be able to launch the coming soon page tomorrow.

Once that goes up, we'll have a Steam community hub that should let us communicate a little better. Hopefully with enough momentum we can launch the real game in a few months.

Sweet! Last update/post here was May, same with the subreddit, so I was curious. Thank you.

Hey, are you still working on this?

Alright will do!!

Thanks man! The best thing anyone can do is let friends know about the game if they would be interested. Even though it doesn't sound like much it really is the most important thing because games live and die by who knows about them, and I can only spread the word so much on my own.

The main reason I don't have a release date yet is because it's so hard to predict when the game itself will be complete. I can feel it getting closer though. Most of the high priority issues are fixed and the gameplay flows a lot better now than it used to.
