Ratz

What is Ratz?

Ratz is a short first-person lane shooter built around incremental progression. The player takes the role of a rookie exterminator heading out on a very first contract, and what should have been routine work turns into a nightmare once mutant rats overrun an entire town.

A mentor is on hand to show the ropes, and the game keeps his motives deliberately murky: whether he is genuinely helping or simply making money off someone else's bad day stays an open question. His method is old-fashioned, letting the rats come forward and cutting them down before they arrive, which he counts as half the job already finished.

The result is a compact low-poly shooter with a clean arc. Hold the line, gather resources, upgrade the kit, and eventually face the Mother Rat behind the infestation. It is framed as a small proof of concept for a much larger game rather than a sprawling finished campaign.

How to play

Play happens along four cardinal-direction lanes. The player switches between them with WASD and shoots with the left mouse button, using a crossbow to drop mutant rats before they close the distance. Standing ground is the intended rhythm of a fight rather than roaming a map, so positioning is about picking the right lane at the right moment.

Rat Mounds are scattered around town and can be destroyed to harvest Green Crystals. Those crystals are the currency for weapon upgrades, and they also fund a larger purchase: the Bolt-O-Matic 8000, the mentor's own invention, pitched as an excessively powerful weapon for professional extermination.

Killing rats also feeds XP. Levelling up earns AP, which is spent at the campfire on stat upgrades, so a run grows along two tracks at once: gear bought with crystals and personal stats bought with AP.

Progress is gated by three distinct waves of mutant rats that grow harder each time. Clearing them opens the confrontation with the Mother Rat, the source of the infestation.

Controls

WASD handles movement, and it is tied to four cardinal-direction lanes rather than free roaming. Pushing between lanes repositions the rookie along the lines the rats use to approach, which makes lane choice the main positional decision in any fight.

The left mouse button fires the crossbow. Because the mentor's whole approach is to let the rats come forward, shooting happens from a held post, and the work is keeping the chosen lane clear instead of chasing enemies down.

Spending happens away from the fighting. Green Crystals harvested from Rat Mounds buy weapon upgrades, while AP earned from levelling is spent at the campfire on stat upgrades, so a run alternates between holding lanes and improving the exterminator.

Tips for your first run

The first day on the job rewards patience more than speed. Rats come to the player by design, so the crossbow work is about timing and lane discipline rather than aggressive pushing. Spend the quiet moments between waves on the town itself.

Two currencies are running at once. Crystals come from Rat Mounds and pay for weapons, while AP comes from levelling and pays for stats at the campfire. Falling behind on either one makes the later waves and the Mother Rat fight noticeably harder.

• Shoot early in the lane rather than waiting for rats to close in.
• Break Rat Mounds whenever a lane goes quiet, since crystals gate weapon upgrades.
• Save crystals toward the Bolt-O-Matic 8000 if raw firepower matters more than small purchases.
• Spend AP at the campfire as levels arrive so stat upgrades carry into all three waves.
• Treat each wave as a step harder than the last and use the gaps to spend what has been earned.
• Keep something in reserve for the Mother Rat rather than emptying everything on the third wave.

Content and replayability

The structure is tight: three waves of mutant rats, each more difficult than the one before, followed by a boss encounter with the Mother Rat. That gives a run a clear beginning, middle, and end, with the escalation between waves doing the pacing work.

Replay value sits in the two upgrade paths. Weapon upgrades bought with Green Crystals and stat upgrades bought with AP at the campfire can be prioritized differently, and the Bolt-O-Matic 8000 is a long-term purchase that changes how the back half of a run feels once it is finally affordable.

The game is explicitly a small proof of concept for something bigger, and player feedback is meant to help decide whether it grows beyond that. For a first-day launch, that makes it a short, complete slice rather than a long-term progression game, and worth approaching as a compact look at a system that could expand.

Presentation and performance

The look is deliberately retro. Ratz is a low-poly 3D first-person game with a PlayStation-era aesthetic, and the town setting carries that style through its lanes and infested streets. Enemies are mutant rats, and the Mother Rat gives the small cast a clear focal threat.

Credits split cleanly. Artwork, story, and character concepts come from Rottenflassh, while programming, game design, story, sound design, and music are handled by Denny'sGuy, so the audio and the character work share a single authored vision.

Ratz runs as an HTML5 game in the browser, and a downloadable build is offered as the best possible experience. Anyone with a browser and a mouse and keyboard can start immediately, which suits a short shooter built around quick lane-based sessions.

Who should play it

Players who like lane shooters with a fixed firing position will recognize the rhythm immediately. The crossbow, the four approach lanes, and the mentor's let-them-come philosophy make for a stationary, aim-focused kind of first-person shooting rather than movement-heavy combat.

Incremental-game fans get two progression currencies and a big-ticket weapon to chase in the Bolt-O-Matic 8000. Anyone who enjoys watching numbers and gear come together across a short run will find the crystals-and-AP loop familiar and easy to read.

It also suits players after a compact session: three waves plus a boss is a defined arc, and the low-poly PlayStation-inspired presentation appeals to anyone nostalgic for that era of 3D. Completionists should note that the game presents itself as a proof of concept, so the content is a slice rather than a long campaign.
