Aliens vs. Ghosts

You play as an alien invading Earth, fighting waves of ghosts in a first-person shooter. You can play alone or team up online in co-op.

Choose from different classes and build them with upgrades. Combat options include electricity, heat rays, portable nukes, an upgradeable exoskeleton, and minions such as robots and UFOs.

Fight through maps, earn money for upgrades and respecs, and unlock weapons by defeating large waves. Quests, hidden items, and puzzles can lead to boss encounters.

Players who enjoy the game often praise its class variety, unusual weapons and minions, and boss fights; some also like playing through waves with friends and mention the art style or music. Reviews also repeatedly ask for more maps and updates, and some find the objectives hard to work out or the waves repetitive. Opinions on difficulty differ, with some calling the game challenging and others saying it is too easy.
