Strategy video game Green and Grey is a classic tower defense adventure. Unlike many similar projects, randomness has a huge impact on the gameplay, as it can throw up locations, conditions for victory, and also adjust the number of opponents and the overall difficulty of the advancing waves at its own discretion. According to the tradition of the genre, the action takes place in a fictional fantasy universe, where the gamer becomes the manager of a small town – and it is this town that needs to be protected from ruin.

Green and Grey offers the user to evaluate the following gameplay features:

• 15 challenging levels, which are united by a single storyline;
• about 20 types of enemies – each with unique characteristics and types of attacks;
• significant variety of resources that need to be mined for the development of the settlement and the construction of defensive fortifications;
• a system of dynamic change of time of day and weather conditions that affect the difficulty of the passage;
• There are bosses who lead the attack of mobs – battles with them are especially difficult.

To survive the attack, the user needs to competently build defensive towers that continuously fire at the enemy. To create a truly effective defense, it is important to carefully distribute resources so that they are enough for all buildings. Actions occur in real time, which forces the player to make decisions as quickly as possible and adequately respond to the situation.
