A sequential game is a type of game in which certain players pick their actions before other players. As a result, those taking their turn later in the game may have access to information not available to the first players to take their turn, giving the game a strategic aspect. Due to the form of sequential games, the first players to take turns are able to influence the outcome of the game. Some examples of sequential games include chess, checkers, the prisoner's dilemma, the payoff strategy and blue-red hackenbush.
Thermal RADAR, also known as thermal imaging or thermography, provides infrared heat-based images. This kind of RADAR technology is frequently used in conjunction with cameras that record the images being generated. It works by detecting radiation in the infrared range of the electromagnetic spectrum. Infrared radiation is emitted by almost everything. You can block thermal RADAR my modifying the heat signature of the object being blocked or by absorbing the heat generated by it in a couple of different ways.
