Rules & Scoring
Game Rules
- 1Your character auto-aims toward the nearest enemy, so focus on positioning and firing
- 2Four enemy types appear: headcrabs (fast, small), zombies (slow), soldiers (medium speed), and vortigaunts (medium speed)
- 3Each bullet deals 15 damage; enemies have 25 + (level x 5) health, so tougher enemies require more shots
- 4Enemies that reach you deal 10 damage to your 100 HP health bar
- 5Clear all enemies in a wave to advance to the next level, which spawns more and tougher enemies
Scoring System
You earn 100 points for each enemy eliminated. Waves grow larger each level (3 + level count), and enemy health increases, so higher levels yield more points per wave.
Tips & Strategies
Beginner
- Keep moving at all times - standing still lets enemies surround you
- Focus on headcrabs first since they are the fastest and will reach you quickest
- Stay near the bottom of the screen so enemies have to cross the entire arena to reach you
- Tap Space rapidly rather than holding it, as each press fires one bullet
Advanced
- Kite enemies by moving perpendicular to their approach path while firing
- Prioritize high-speed enemies (headcrabs move at speed 2) over slower zombies (speed 0.8)
- Use the corners to funnel enemies into a single approach direction for easier targeting
- Keep track of enemy count - when only 1-2 remain, position yourself near center for the next spawn wave
- Learn the auto-aim behavior: your aim snaps to the nearest enemy, so position yourself so the nearest enemy is the one you want to kill
Pro
- Master circle-strafing to keep maximum distance from all enemies while continuously firing
- In later levels, enemies have over 50 HP requiring 4+ shots each - plan your ammo timing accordingly
- Aim for survival streaks past level 10 where enemy waves exceed 13 creatures at once
- Optimize your movement to never get cornered since enemies respawn at random positions after hitting you

There are four enemy types: Headcrabs are small and fast (speed 2), making them the most dangerous early threat. Zombies are large but slow (speed 0.8). Soldiers move at medium speed (1.2). Vortigaunts also move at medium speed (1.2) but appear as purple enemies. All enemies chase you relentlessly and deal 10 damage on contact.
You earn 100 points for each enemy you destroy. Each level spawns 3 plus the current level number of enemies (so level 1 has 4 enemies, level 5 has 8, etc.). Enemy health also increases each level (25 base HP plus 5 per level), meaning later waves take more shots to clear. Your goal is to survive as many waves as possible and rack up the highest score.
