A top-down bullet-heaven on wheels: drive an endless zombie-choked highway for three minutes, auto-firing at anything that gets close while picking one of three upgrade cards — multi-shot, chain lightning, a meteor strike and three more — every time you level up.
Shell Squad 3D (弹壳特攻队-3D) drops you into Zero Point District (零点街区), a top-down bullet-heaven where your car drives itself down an endless highway while you steer between lanes and it auto-aims and auto-fires at anything that gets close. The title card's own line for it: "Cross the corpse tide, pick up hope — give the three minutes before dawn to yourself" (穿过尸潮，拾起希望。把黎明前的三分钟，留给自己。). A survival clock counts down from 180 seconds; a kill counter climbs as the car fires.

Killing zombies and salvage-truck obstacles drops XP gems; picking one up enough times levels you up and offers a choice of one of three upgrade cards from a pool of six — multi-shot, enhanced ammo, an emergency heal, a speed sprint, chain lightning and a meteor strike — read off their icons on the lower HUD.
How to play Shell Squad 3D
- Click 开始行动 (Start) on the title card.
- A and D change lanes; W and S also register as movement. You never aim or fire directly — the car does that on its own at the nearest target.
- On a phone, drag on the road instead; the same auto-aim and auto-fire apply.
- Grab the small white shards that drop from kills — they are the experience pickups the HUD calls 经验宝石.
- When the experience bar fills, pick one of three offered upgrade cards. Survive the full 180-second clock (雪崩距离/生存180秒) to finish the run.

Why it's worth your time
It reads as a driving reskin of the "survivors-like" bullet-heaven genre — auto-aim, auto-fire, run past danger, pick an upgrade — set on a scrolling highway instead of an open field.
The car, road and zombies are rendered in the same low-poly voxel style as the other three games in this posting batch, on a genuine WebGL2 canvas rather than flat sprites.
The HUD relabels itself slightly for touch: the desktop title screen describes controls as "移动车道" (change lanes), the phone version says "移动躲避" (move to dodge) instead, for the same underlying drag-to-steer input.
How it was made and where it lives
Hosted on the author's own page. The author publishes as sonic0828. Original: https://iamsonic.net/2026/mini-games/shells-3d/play.html. The Play button above runs our own unmodified copy, so the game keeps working here if that page goes down — which on free hosting usually has nothing to do with the author. Nothing about the game itself is changed, and the original stays linked from every page.
