Blocky Siege
By G55.CO
Blocky Siege drops you into first-person gunfights on voxel-built maps, where you play a special forces soldier and trade fire with other players until the round is decided. You carry three weapons and switch between them with the number keys, watching your HP and ammo counter in the corners of the screen. It runs free in a desktop browser with no download.

How to Play Blocky Siege
You spawn with a full 100 HP and a rifle in hand — the frames show a FAMAS with a 27-round magazine and a large reserve pool. Move with WASD, jump gaps with Space and drop into a crouch with C to shrink your profile behind low block walls. Left mouse fires, right mouse pulls the gun up for a more accurate aimed shot, and R reloads before you get caught empty.
Maps are built from chunky textured blocks: wooden interiors with open windows, stone-walled courtyards, grass yards with thick tree trunks and raised towers. That layout gives you plenty of corners, stairs and rooftops to fight around, so most kills come from spotting a rival player crossing an open lane before they spot you.
A round timer counts down at the top of the screen, and other players' chat messages appear on the left — press T or Y to type back. Keys 1, 2 and 3 pick between your three weapons, and P opens the pause menu.
Tips
- Reload with R the moment a fight ends — the magazine holds 27 rounds and you do not want to be topping up mid-duel.
- Use right-click aiming for shots across the long stone courtyards, and hip-fire indoors where fights happen at a couple of blocks' distance.
- Crouch behind the low block railings and window ledges; they cover most of your body while you watch a lane.
- Learn which of your three weapons suits close wooden corridors and which suits open rooftops, then switch with 1, 2 or 3 before you push.
- Keep an eye on the round clock at the top of the screen so you know how much time is left to swing the result.
