About the Game
BURN BRIGHTER!! INITIATE DRY CONTACT!! 30 bosses await in the insurmountable run-and-gun!!!
----- STORY -----
As Earth reaches the precipice of apocalypse, a lone boy with vengeful eyes rushes towards KaiserCorps, the leading authority on weapons technologies and the epicenter of an alien rampage. Discover the backstory of Geverel, the hollow soldier, through non-linear storytelling with comic-style art.
----- GAMEPLAY -----
Burst through 8 stages, each loaded with 1-on-1 duels against KaiserCorps' insane experiments and top infantry. Go blazing with 4 different types of guns, then slam a centrifuge of raw energy into your enemies with the Tatsujin Punch and Ignition Dash Explosion.
(Disaster Arms is intended to be played in one sitting with limited continues like an arcade game - however, an unlimited continue mode is provided for casual and newcoming players.)
----- FEATURES -----
30 bosses - from giant machine-monster hybrids, to your vengeful soldier brethren
Shmup/Bullet Hell design philosophy meets action platformer!
Stylish artstyle and multi-sprite animation
Strafe-based shooting controls let you evade while keeping your aim on the target
Strike enemy weakpoints for maximum damage
Distinct pre-apocalypse setting: Prevent the incoming dystopia!
Original soundtrack composed using YM2612+SN76489, the signature sound hardware of the 16-bit MD/GEN consoles

Disaster Arms 1.1 is live!
The following changes are included:
STG Training Mode
-Replay any previously completed stage, with your choice of difficulty, HP and starting Meter
New Hidden End-Boss in Act 3
(I'm not going to spoil what it is or where to find it. Here's my only hint: Play well on Advance/Impact, and an item in Act 3-3 may appear)
Other changes:
-Double-tap to punch can be toggled on/off in the Options menu
-Tap 'super' to switch weapons can be toggled on/off in the Options menu
-You can now double-tap down to fall through Jump-thru platforms (check the options menu)
-Fall speed after jumping through a Jump-thru was increased. This was done to address a bug where you would re-magnetize to the platform after jumping on certain PC framerates.
As a side-addendum, Disaster Arms reached 500 purchases as of January 2026! Thank you as always for the support, and please look forward to more PD_CGT project news in the coming months :)
-David Peters
-'Restart from Act 1' now correctly resets your HP
-Candy Rangers has been added to the Other Works page
-Punching is temporarily disabled after falling in a pit so the player can't punch and fall through the offscreen collider
-8-3 has a glitch where the player may accidentally fly upwards OOB if hit by the giant laser while touching a ceiling corner. I wasn't able to find a fix for the bug itself, but I've added an off-screen ceiling so the player can jump back down in the event it occurs :/
-The 8-3 laser's death animation will now trigger the stage boss' introduction even if killed with the Ignition Dash
-Added larger tiles to borders of 5-2 to reduce odds of being knocked OOB
-Boss 8-4 could accidentally be killed on an early phase by dealing enough damage with the ignition dash. This has been fixed.
Please continue to report anything you have trouble with and I'll do my best to fix as needed
