Build modular ships, spend metal on the tech tree, and push deeper into scaling field sectors.
n-gon
n-gon is a free modular roguelike shooter from Landgreen, shipped as a browser HTML5 build you can launch in an iframe without a store install. Controls map cleanly to keyboard, mouse, or touch, and the same client runs on desktop Chromium and mobile Safari for shared-laptop or phone sessions. Cold loads stay light enough for school or cafe networks that block heavier launchers. In n-gon, that feedback shows up within a single retry rather than after a long load screen.
What defines n-gon is readable systemic feedbackâÂÂwhether launch cones, stamina bars, zone timers, restock queues, or balance metersâÂÂthat lets you correct the next attempt in the same sitting. That clarity keeps short breaks productive while still separating casual clears from clean high-score routes across repeated runs of n-gon. Watching the live iframe while you read keeps n-gon mechanics tied to what the HUD actually shows. Because n-gon resets quickly, you can verify one change before stacking a second adjustment.
Landgreen paced the HTML5 client for minutes-long sessions: fails reset quickly, critical meters stay on screen, and goals read within the first moments of a clip. The pace suits classroom gaps, couch handoffs, and stream overlays where viewers need to understand n-gon within seconds. Because n-gon resets quickly, you can verify one change before stacking a second adjustment. Players who treat n-gon as a readable system climb faster than those who mash without checking meters.
Because this guide embeds the playable build on the same URL, transferring a tip into a live n-gon test costs almost no context switch compared with juggling mirrors, unrelated ad lobbies, or outdated screenshots that disagree with the current client. Players who treat n-gon as a readable system climb faster than those who mash without checking meters. The HTML5 client makes those checks cheap: reopen the tip, test once, then continue the route.
Start a Field Run and open TechLedger without buying yet. Keep focus inside the n-gon iframe so inputs stay mapped. Check that the relevant n-gon cue moved before you advance. On a miss, repeat this n-gon step once so the habit sticks.
Purchase a cheap defensive node, then a damage node. Check that the relevant n-gon cue moved before you advance. On a miss, repeat this n-gon step once so the habit sticks. Keep focus inside the n-gon iframe so inputs stay mapped.
Mount a rear thruster and feel SocketThrust mobility. On a miss, repeat this n-gon step once so the habit sticks. Keep focus inside the n-gon iframe so inputs stay mapped. Check that the relevant n-gon cue moved before you advance.
Clear a boss and immediately plan spends for SectorScale. Keep focus inside the n-gon iframe so inputs stay mapped. Check that the relevant n-gon cue moved before you advance. On a miss, repeat this n-gon step once so the habit sticks.
Push one more sector with the new budget intact. Check that the relevant n-gon cue moved before you advance. On a miss, repeat this n-gon step once so the habit sticks. Keep focus inside the n-gon iframe so inputs stay mapped.
Try Boss Rush once burst tools are unlocked. On a miss, repeat this n-gon step once so the habit sticks. Keep focus inside the n-gon iframe so inputs stay mapped. Check that the relevant n-gon cue moved before you advance.
TechLedger shows exact metal prices on each weapon branch, turning the tree into a budget sheet rather than a mystery unlock wall. In n-gon, that feedback shows up within a single retry rather than after a long load screen. Watching the live iframe while you read keeps n-gon mechanics tied to what the HUD actually shows. Because n-gon resets quickly, you can verify one change before stacking a second adjustment.
SectorScale multiplies difficulty by one-point-fifteen after bosses, so unused metal after a clear is a planning error for the next field. Watching the live iframe while you read keeps n-gon mechanics tied to what the HUD actually shows. Because n-gon resets quickly, you can verify one change before stacking a second adjustment. Players who treat n-gon as a readable system climb faster than those who mash without checking meters.
SocketThrust grants two-tenths mobility per rear thruster mount, rewarding modular investment in kiting as packs densify. Because n-gon resets quickly, you can verify one change before stacking a second adjustment. Players who treat n-gon as a readable system climb faster than those who mash without checking meters. The HTML5 client makes those checks cheap: reopen the tip, test once, then continue the route. In n-gon, that feedback shows up within a single retry rather than after a long load screen.
Field Run mixes trash and shops; Boss Rush chains bosses with less farm, shifting value toward burst nodes early. Players who treat n-gon as a readable system climb faster than those who mash without checking meters. The HTML5 client makes those checks cheap: reopen the tip, test once, then continue the route. In n-gon, that feedback shows up within a single retry rather than after a long load screen.
Before leaving a shop, read TechLedger totals for the next two planned nodes so metal is not stranded on a vanity gun you will not equip. Use that cue read on the following try instead of reinventing the plan mid-panic.
Immediately after a boss, spend toward survivability because SectorScaleâÂÂs one-point-fifteen rise hits before you feel ready if you stroll into the field broke. Use that cue read on the following try instead of reinventing the plan mid-panic. Tie the fix to a visible n-gon meter so the change stays measurable.
Mount at least one rear thruster for SocketThrust as soon as sockets allowâÂÂlate-sector packs punish immobile polygons hard. Use that cue read on the following try instead of reinventing the plan mid-panic. Tie the fix to a visible n-gon meter so the change stays measurable.
In Boss Rush, prioritize burst branches over slow DoT trees that needed Field Run trash time to shine. Use that cue read on the following try instead of reinventing the plan mid-panic. Tie the fix to a visible n-gon meter so the change stays measurable.
If a modular part blocks a thruster socket, rearrange before the next sector rather than carrying a high-DPS but immobile shape. Use that cue read on the following try instead of reinventing the plan mid-panic. Tie the fix to a visible n-gon meter so the change stays measurable.
