Alien Grounds

Alien Grounds is a fast-paced sci-fi first-person shooter built around arena combat against relentless enemy hordes. You take on short missions, build mastery through repeated runs and face escalating pressure, with a light roguelite structure.

Missions and scores

Each mission is a short run with its own score. Completed mission scores contribute to your Overall Score, and you can move on to the next mission or replay one to improve your result. Progress saves after each completed mission.

Your Overall Score is ranked on monthly and all-time leaderboards. Top monthly players are added to the Hall of Fame. You can raise your score by landing headshots, shooting fireballs, knocking enemies off the map, using the gravity gun at high speed, using the pistol, avoiding powerful weapons, and playing higher missions or harder difficulty levels.

Enemies

You face four types of enemies:

• Runner: moves quickly and lands light hits.
• Tank: moves slowly and lands heavy hits.
• Shooter: keeps its distance and fires.
• Phantom: is subtle and difficult to see.

Weapons

The game offers seven weapons, each with different uses and trade-offs:

• Pistol: deals low damage and has limited ammunition.
• Automatic Rifle: deals standard damage, with recoil and spread; its ammunition refills when low.
• Laser Gun: deals standard damage with infinite energy and no recoil, but overheats if used too much.
• Gravity Gun: deals standard damage with infinite energy and no recoil, but speeds up the fight.
• Annihilator: a close-range panic button with a short recharge.
• Chem Gun: poisons enemies; kills trigger after enough enemies have been poisoned.
• Freeze Gun: locks enemies in place for area control, with a slow recharge.

Difficulty levels

Choose from three difficulty levels:

• Easy: a relaxed, forgiving setting for learning the systems.
• Medium: the intended experience, where balance and precision matter.
• Hard: deadlier enemies, tight resources and the highest multipliers.
