Alien Grounds:  FPS Challenge

Battle wave after wave of robots in this fast-paced sci-fi FPS. Use powerful alien weapons, stay on the move, and fight to stay alive as the battlefield keeps changing. How long can you last?

Mission:  Survive and score

The challenge starts easy, but don’t get comfortable. Each wave grows deadlier, forcing you to adapt, scavenge, and fight smarter. The number of enemies keeps growing — until there’s nowhere left to run unless you mow them down with firepower. Use brief pauses between waves to reload, grab supplies, and brace for the next assault.

Score System

Precision matters — every kill earns you points. Headshots, phantom kills, and clean knockbacks are worth more. But beware — revives come at a cost. Perfect your aim, master your skills, and climb the leaderboard!

Dynamic Maps

No two battles are the same! Maps shift and evolve as the fight progresses, transforming from dark, ominous arenas to bright, scenic landscapes. Adapt to the terrain or use the Portal to lock in your favorite battlefield.

Do you have the skills to survive and dominate? Jump into the alien grounds and find out. Good luck, soldier!
