BTD BTD prioritizes simplicity, user-friendliness, and realistic game balance. Designed with straightforward functions, the game aims to be accessible for first-time players. Gameplay allows for easy initiation without the need for extensive pre-game preparations. Despite the approachable design, combat difficulty is far from casual. Similar to real-life consequences, BTD BTD imposes serious repercussions when attacked, leading to potential death. However, in contrast to reality, players have the immediate opportunity to retry after facing defeat. A discharged projectile travels, influenced by both air resistance and gravity. These effects vary depending on the warhead type. Upon impact, the projectile may either penetrate or ricochet, influenced by factors such as the material, thickness, angle, bullet speed, and warhead type.
