Gotcha! The Sport! is a video game for the Nintendo Entertainment System that was released in 1987; it uses the Nintendo Light Gun and is considered to be a capture the flag-style game played with paintball guns loaded with simulated paintballs. The player's mission is to get through the level, capture the enemy flag by shooting it, and return it to your base. This is while simultaneously trying not to get shot by the other team, run out of ammo, or run out of time. A light gun is necessary for this game, but one needs to also use the controller. The directional pad will move the screen left and right. Ammo boxes can be found sitting on the ground or carried by enemies in the background. Interestingly, it seems that only misses cost you ammo, so if one's aim is precise, they will receive a significant bonus for leftover ammunition.
There are three levels in the game: Woods, Warehouse District and Snow Fields. The Woods and Snow Fields levels feature enemies in military garb, while the Warehouse District features enemies modeled after early 1980s punks. These rounds repeat in this order infinitely; each time around, the reaction time needed for the enemies to aim and fire is reduced.
