In this approach, the player unlocks new units or abilities as they progress through the game. This allows the game to introduce new elements at a pace that is appropriate for the player’s skill level.
An example of using a tier system in a tower defense game might look like this:
-
- Begin by giving the player access to a limited arsenal of defensive towers. These towers should be relatively weak, but cheap and easy to use.
- As the player progresses through the game, unlock new tiers of towers that are more powerful but also more expensive and slower to build.
- Use playtesting to fine-tune the balance of the game. Pay attention to how the player is using the different tiers of towers and make adjustments as needed to ensure that each tier feels distinct and useful.
By following this approach, you can create a tower defense game that allows players to unlock new and more powerful towers as they progress through the game. This can provide a sense of progression and reward for players, while also ensuring that the game remains challenging as the player gains access to more powerful options.
