Description
One Rotten Oath is a story-driven FMV+FPS hybrid with horror elements. Created by the director of A Trip to Yugoslavia.
It's been years since humanity enjoyed its last normal day. Everything lost its meaning, when a mysterious chemical compound leaked from one of the nearby laboratories on the edge of town. Today this event is known as, The Leak.

Chaos consumed the streets and crept into the lives of everyone. Over time, the people who had been exposed to chemicals for too long turned into monsters. Fast, ruthless creatures, driven only by instinct. Those who could, have long since fled. The lucky ones hid in bunkers, some built by themselves and others hidden deep in archival plans of the city. The unlucky ones are slowly dying, or worse.

The game puts you in the shoes of the survivor, whose job is to protect the other people who are still trying to lead a normal life in a bunker. A normal night watch turns deadly, when the only working generator malfunctions and turns off in random intervals for 60 seconds.

Features:
2D rotoscoped sprites in 3D environments. Enemies and NPCs are cut out manually frame-by-frame. Everything is made out of about 3000 frames in total.
FPS time-based defense game with First Person Tank Controls.
FMV cutscenes with visual novel elements.
Various enemy types e.g masked mutants or mutated football players.
Use the rifle, revolver and double barrel shotgun to defeat the threat.
Defeat enemies and defend barricades in a small forest area.
Utilize trapdoors and kicking to keep enemies at bay.
Use the sound cues and sensors to pinpoint the enemy’s location.
Original soundtrack composed by Olga Lewińska.
