Match Replay (2D & 3D)

Every match in 5Stack can be replayed straight from the browser — no CS2 install, no downloading the demo. As soon as a demo is parsed, each map gets a 2D (radar) and 3D replay you can scrub through.

Replay reconstructs the round from the parsed demo data. It does not stream video, so it loads instantly and works on any device. For a true GOTV-style video feed with player POVs, see In-Browser Demo Playback.

2D Replay (radar)

A top-down view on the map's radar image. You get:

• Timeline scrubbing with a progress indicator, and playback speeds from 0.5× to 8×.
• Kill feed — killer, victim, weapon, and headshots.
• Utility — smokes, HE, flashes, molotovs, and decoys, including throw trajectories.
• Bomb events — plant and defuse locations.
• Buy round overlay — each team's economy and loadout at the start of a round.
• Player equipment — weapons, grenades, armor, bomb, and defuser per player.

3D Replay

The same round rebuilt on the map's real geometry, rendered with WebGL:

• Camera modes — orbit, follow a player, or top-down.
• Right-drag to free-look, middle-drag to pan, scroll to zoom.
• Roof-cut slider to hide the upper part of the map so you can see the action underneath.
• Utility heatmap showing where grenades land most, plus a "ghost" of the thrower for a selected nade.
• All the same kill, bomb, and equipment data as the 2D view.

Replays open in their own window so you can keep the match open alongside them.

HUD

Both views share the same HUD — live scores, round timer, bomb timer, and the kill feed. You can toggle it on or off while watching.

Map geometry

3D replay loads a lightweight collision mesh for each map. When a mesh isn't available for a map, the 3D view automatically falls back to the flat radar, so replay always works — the 3D geometry simply improves once the mesh exists.
