You spoke, and we listened! We're putting Chain Reaction 2023, the Classic Chain Reaction 2015, and Swordplay, our Fantasy game in one download. Play any and all genres any way you want! 

Modern, Sci-fi and Fantasy? Zombies too?

Yep, all this and much more... and it's free.

Chain Reaction 2023 is a set of man-to-man combat rules that can be played in a variety of periods and with any figures you may already have. Modern, WW2, Medieval, Sci-fi, Fantasy and yes, even Zombies.

Chain Reaction 2023 is an introduction to all Two Hour Wargames games. Games are very fast, just like real gunfights, and multiple games can be finished in two hours or less. Chain Reaction 2023, like all THW games, is designed to be played solo, cooperatively – all players on the same side – or competitively – head-to-head.

Play it on the tabletop with any figures you may already have. Play it on the Battle Boards with Counters – we’ve given you both. Play it any way you want because after all…

It’s Your Game!
