Prototype TD

Prototype TD is a tower defense game with roguelike elements. Each game gives you a different map and selection of towers and bonuses, so you must adapt your defenses to the situation.

Build the map

Each game starts with a randomly generated map. You place blockers to shape the routes enemies take, then choose where to build towers. The layout affects which combinations of walls and towers will work best, encouraging you to rethink your approach each time.

Choose your defenses

The game has different tower types and bonuses, but they are not all available in every game. After every 5th round, you choose from a randomly selected set of bonuses. You must weigh what suits the current map and decide which tower combinations to pursue; across multiple games, you may need to use each tower type when the situation calls for it, or pass up a strong tower that does not fit.

Towers deal damage or interfere with enemies in different ways. Upgrades let you focus on heavily boosting one tower or spreading upgrades across many towers. Which approach works depends on the towers and boosts available in that game.
