Headstrong is 2D mobile game which has the player defending against giant robotic monsters by first intercepting them and then killing them. The game takes place in the area from the moon to the earth and the objective is to stop as many enemies as you can. The player will start very close to the moon and will be able to engage enemies by hitting a button when they get close to them. During a takedown, the player will be prompted with a little mini-game which has the player doing puzzles or time-attack challenges and if the player is successful, the enemy dies otherwise the player has to spend more time chasing them down and doing it again. It's important to note that enemies can get past the player, but to help with that, the player is always just a little faster than the enemies and is able to get certain upgrades after each eave is complete.
