CS2-10k: A Large-Scale Egocentric Counter-Strike 2 Dataset
CS2-10k is a large-scale egocentric gameplay dataset built from professional CS2 matches. It contains 600,000+ player-round videos spanning 10,000+ hours of first-person footage, paired with per-frame annotations covering keyboard state, mouse movement, and 3D player trajectory.
CS2-10k is built from public professional match demos sourced from HLTV. For each demo, we render first-person video at 720p, 48 fps using the demo replay tool inside CS2, producing one video per player per round. Alongside each video, we store a .parquet file containing per-frame annotations synchronized to the video timeline.
The dataset is published in WebDataset format: ~2 GB tar shards under data/<map>/, where each sample is a <uuid>.mp4 video paired with its <uuid>.parquet annotations. A top-level index.parquet lists every clip with its shard location for lookup and filtering.
Annotation schema
Every video clip has its corresponding annotations stored in a .parquet file:
| Field | Type | Description |
|---|---|---|
map |
string | Map name (e.g. "mirage", "dust2") |
round_number |
int | Round within the match |
team |
int | 0 = Terrorist, 1 = Counter-Terrorist |
num_frames |
int | Total frames in the clip |
fps |
float | Video frame rate (48.0) |
total_time |
float | Clip duration in seconds |
fov |
float | Camera field of view (90.0°) |
frame_data |
list[dict] | Per-frame annotation array (see below) |
Per-frame annotations
Each entry in frame_data contains:
| Field | Description |
|---|---|
actions |
Concatenated active keys: W/A/S/D (movement), J (jump), C (crouch), R (walk), V (freefall), [ (fire), ] (scope/secondary), - (no input) |
mouse_x_delta |
Horizontal camera delta — proxy for mouse X movement |
mouse_y_delta |
Vertical camera delta — proxy for mouse Y movement |
position_x / y / z |
Player world position in game units |
rotation_yaw |
Camera yaw angle (−180° to 180°) |
rotation_pitch |
Camera pitch angle (−90° to 90°) |
