Use to play this back in Jr High tons along with many other Half-Life mods. Been a blast getting back into.

i got to tell you it was perfect, everything down to the last detail

An excellent game, really nothing scratches that itch of team coordination of the old early 2000s era commander-infantry style games nowadays. Every team based multiplayer game nowadays nobody speaks a whisper and everybody mutes all chat or the devs do it for you.

Natural selection 2 was one of those games where on each team you had at least 1 person on mic every game, usually the commander when building structures or helping out his little troops dropping some ammo/meds while leading his team.

Now as for the caveats. This game will filter you if you are new, especially today since it stopped being updated 2 years ago. And the only people who play the game nowadays are hardcore veterans that while mostly friendly to newcomers, will just chainkill you over and over again no mercy. There are support roles for aliens and marines that mitigate this somewhat but when servers are generally empty and the games you do get result in you getting stomped its tough.

Even through all that you can really tell this game was made with passion and It will always be one of my favourite games despite its current state.
