Brutal, Fast, and Free

Alien Grounds is a no-nonsense, fast-paced FPS where the difficulty ramps up fast.
It starts easy. Then it gets personal... and addictive.

• Hard mode that earns its name – no tutorials, no mercy 

• Easy mode available – for training or casual play

• Every shot counts – smart aiming = higher scores

• Maps shift mid-battle – no two runs feel the same

• Steam achievements – brutal challenges only a few will ever earn

• Instant action – no cutscenes, no waiting, just fight

You’ll die. You’ll retry. You’ll get better.
And if you make it to Mission 100 on Hard… you’ve earned bragging rights.

Weapons

• Pistol – Low damage, limited ammo. Best used for headshots. Starts in Mission #1.

• Automatic Rifle – Recoil, bullet spread, and a scope. Ammo resupplies when low. Unlocks in Mission #2.

• Laser Gun – No recoil, infinite energy, scoped – but it overheats with sustained fire. Unlocks in Mission #3.

• Gravity Gun – No recoil, infinite energy, scoped – but it speeds up time. Unlocks in Mission #4.

• Annihilator – Annihilates nearby enemies. Short recharge delay. Activate with middle mouse button. Unlocks in Mission #5.

• Chem Gun – Won’t kill a single enemy, but devastating against groups. No ammo or recoil. Unlocks in Mission #10.

Just play it!

No microtransactions. No paywalls. Just a solo dev making a game that's fun, fair, and deadly.
Hit Play and see how far you can go.
