How to Play B1F: Dungeon Massacre
B1F: Dungeon Massacre is a top-down survivor built around a single control: drag anywhere on the screen to move your character, and your weapon fires automatically at the monsters closing in. The embedded start screen states the goal directly — "SURVIVE 20 SECONDS!" — under the instruction "DRAG to move — weapons auto-fire."
Each level raises the survival target. Level 1 asks for 20 seconds inside the embedded ad; the fullscreen levels that follow push the target further, with a roughly 31–32 second clock observed on Level 2 and a "SURVIVE 40 SECONDS!" target visible for Level 3. A KILLS counter and a combo multiplier — climbing as high as "x5 COMBO" in observed play — track how well a run is going, and clearing a level with time to spare pays out a time bonus based on the seconds remaining.
The fullscreen levels add a second objective on top of survival: a hint reading "Move to grab gems and power up!" appears once you leave the embedded ad, and small magenta gems scatter across the dungeon floor for your character to collect while dodging monsters. The floor itself is drawn as a checkerboard dungeon tile that shifts from a dark navy on Level 1 to a deep brown on Level 2.
Clearing all 3 levels ends the run on an ALL CLEAR screen with PLAY AGAIN and EXIT buttons. The specific conditions and screen that appear if your character is defeated before the timer runs out were not reached in observed play.
Controls
- Drag anywhere on the screen to move your character; your weapon fires automatically, so there's no separate attack input.
- In the fullscreen levels, move over the small gems scattered on the floor to collect them and power up.
- A combo multiplier climbs the longer you keep killing monsters without a gap.
- Survive until the level's countdown reaches zero to clear it.
Tips & Strategy
Keep moving, don't chase
Because your weapon auto-fires in whatever direction it targets, your only job with the drag control is staying alive and positioned. Circling the edges of the monster crowd rather than diving into the middle keeps your character's exposure lower while the auto-fire does the work of thinning the horde.
Watch the combo, not just the kill count
A combo multiplier — observed climbing to x5 COMBO — sits alongside the KILLS counter and rewards unbroken streaks of kills. Since the auto-fire weapon does the shooting, keeping your character in range of a steady stream of monsters, rather than drifting to empty corners of the floor, is what keeps a combo alive.
Detour for gems once you're in fullscreen
The fullscreen levels add a "Move to grab gems and power up!" hint that doesn't appear in the embedded Level 1. Once you're past the embedded stage, small magenta gems scattered across the dungeon floor are worth a detour on your way around the monster crowd.
Bank a time bonus by surviving with room to spare
A level clear pays out a time bonus scaled to the clock remaining — one observed Level 2 clear banked 320 points from 32 seconds left. Since the survival target only grows across the run (20s, then roughly 32s, then 40s), staying alive comfortably inside the limit rather than scraping through at the last second adds up across all 3 levels.
Use the floor color as a level check
The dungeon floor's checkerboard tint shifts from a dark navy on the embedded Level 1 to a deeper brown once you're into the fullscreen Level 2. It's a quick glance-cue for confirming you've progressed to a new level without needing to look away from the action to check the HUD.
Frequently Asked Questions
Is B1F: Dungeon Massacre free to play?
Yes. It loads directly in your browser with no download or account required.
How many levels does B1F: Dungeon Massacre have?
Three. Level 1 plays inside the embedded 300x300 ad with a 20-second survival target, and clearing it opens a fullscreen page for Levels 2 and 3, which raise the target to roughly 32 and then 40 seconds.
How do I control my character?
Drag anywhere on the screen to move your character around the dungeon floor. Your weapon fires automatically at nearby monsters, so there's no separate attack button to manage.
How do I win a level?
Survive without being defeated until the level's countdown reaches zero.
Is there anything to collect besides kills?
Yes. The fullscreen levels scatter small magenta gems across the dungeon floor that you can move over to collect and power up, alongside the KILLS counter and the combo multiplier that tracks your unbroken kill streak.
