Half-Life: Peaces like Us is a singleplayer modification for Half-Life. Story: Mankind found an entrance to XEN world and an investigation team met with the uncanny aliens in there world. Then, mankind succeeded in becoming allies with them. Later, a scientist team built a joint laboratory in the world of XEN. But, something bad was approaching... Info: An alien is a friend. Don't shoot it! Hint: There is a secret in a certain map. This place seems to fall.
I like the story. The gameplay and puzzles are similar to Half-Life's (in less time, way less). What more original idea for a HL spin-off story than friendly xenians? In fact, those are real friends, providing help at Gordon all along the game. "Another world", however, puts the quota of weirdness, but fortunately in a good way. I like how the anime doesn't fit bad with the ambience, and how the places mix in some parts Xen landscape with lab things. Great mod, with a promising storyline, but should be developed in a more extensive game.
