Featured Projects
The Last Sit
Endless Top-Down Shooter.
➤ DESCRIPTION
An elderly office worker awakes amidst an unexpected apocalypse. As your colleagues transform into wheelchair-bound zombies, your sole motivation lies in a promise made by the CEO: a long-awaited raise in the event of an apocalypse. Experience this unique game where movement is tethered to the recoil of your weapons, adding a layer of strategic depth to the gameplay.
➤ CONTRIBUTIONS
• Designed and implemented the main mechanic: physics-based sliding movement generated by the recoil of weapons.
• Implemented a progression system for the weaponry. Weapons have stats that can be upgraded with coins through the weapon shop.
• Created 3 weapon types with different stats and bullet patterns: revolver, shotgun, and heavy machine gun.
• Implemented most of the UI elements of the game, including a window for a weapon shop and an upgrade shop.
• Added a script to the Pathfinding algorithm that slightly alters the path of every enemy so they avoid taking the same route.
• Implemented a camera lookahead feature so the player can see far ahead in the direction they are aiming at.
• Built the level layout using Unity's 2D Tilemap tool.
