Shooting game - Unity

Write a shooting game between two groups in a house or in an outdoor area that has obstacles and hiding places (not just a forest or an open field). Each team has two fighters, in only one team one of the fighters is a human player (first person). At the beginning of the game, the fighters have no weapons (pistol and/or grenades). The weapon must be found in the field (not inside the house). The guns and grenades are hidden in random places. The players search for the weapon and as soon as they pass it, they hold the weapon in their hand. The human player has to click on the weapon to take it. In order to shoot a gun, you have to press SPACE, In order to throw a grenade, you have to press Q. The stock of bullets or grenades is unlimited. One of the players (the commander) determines the movement while the other player follows him. In a team of the human player, the NPC follows the human player. Each NPC decides on its own when to fire or throw a grenade. The goal of the game is to eliminate the opponents players - the players just move in the field and as soon as they see the opponents attack them. When one of the players is injured or killed and also when the team wins or loses an appropriate message will appear on the screen.
