Tom Clancy's Rainbow Six Siege (Ubisoft, 2015) is a tactical first-person shooter from the well-known Tom Clancy series. In the 5 vs. 5 battles, all players start by choosing an operator and his equipment before they either have to rescue hostages, secure a biohazard container or disarm one of two bombs (or prevent the latter). Both teams have time to prepare before each round. For example, walls can be reinforced, traps can be laid, or mobile cameras can be used to uncover positions.

The basic mechanics of the game are easy to learn, but a lot of time is required to build up a complete understanding of the cards.

The game costs 20 euros in the basic version and can be purchased in various online stores.
