A friend introduced me to Escape the Dark Castle. I immediately had withdrawals and needed to play again!
Dark Sector is a little more involved than Dark Castle, with both ranged and close combat, flank moves and single use per fight med kit (instead of "rest")
Still the same great narrative driven gameplay and enjoyable with up to 4 players. (though you can play solo)
The replay value is great with almost unlimited combinations of chapters and bosses. AND you can buy expansions.
All you need is 1 player who knows the basic rules (a simple GM) then anyone unfamiliar with the game to jump right in and feel a part of the experience as it unfolds.
Very fun, dark-retro-scifi-atmospheric game. Takes 3 min to setup, 30-45 min to pay, and 2 min to tear down. Story based cooperative, where you move through three acts, each with chapters that you have to overcome from traps, stealth, to combat. The dice make it interesting and fun, and the randomization of the story deck keep re-playability high.
