The group I play with all collected 40k many years ago but have no desire to get back into the full armies/long games.
Kill Team was the perfect gateway drug to getting back into the world of GW! Started with the intention of only having one team but that snowballed quickly...
Got Necrons, Tyranids and some Grey Knights plus two warbands for Warcry.
Should be getting my first game of the new edition this weekend, just need to finish building some models.
