Overwatch is a game made by Blizzard Entertainment based heavily on team composition and character choice. There are 5 default modes in Overwatch, in which those included are Payload, Hybrid, 2 Control Point, and King of The Hill. 2 Control point is the worst, as the first point is too far from defense and too close to offense, while the second point is too close to defense and too far from offense. King of The Hill is the best, because its maps are always completely symmetrical, meaning it’s completely on you and your team if you fail. Payload is like 2 CP except the point is moving if enemies are on it, and defense wins if the payload does not make it to the last point. Hybrid is a mixture between 2 CP and Payload, including a first point and a payload. In order for the payload portion to be included, the first point must be captured.
The balance of each game-mode relies on the map, its choke-points, and the flow. KoTH doesn’t have this problem because both sides of the map are exactly the same, just mirrored. KoTH almost entirely relies on how well you communicate with your team and your individual skills. Payload is a generally good mode, but some maps are too tight and some are too open. 2 Control Point is a massive pain to play, as each of the two points are always too close or too far away from someone. Hybrid feels like you’re playing 2CP, with only one control point and a payload. This mode is less enjoyable because it almost always includes a tight choke-point.
Overall, Overwatch is well balanced map-wise outside of 2CP.
