The citadel is a old school first person shooter, if you liked DOOM 1 and 2, Duke Nukem, Quake etc u will feel at home gameplaywise. Ambience and story are pretty dark, minimalistic in term of explicit narration. Music is very good and serve a narrative purpose with brio. Guns are fun to play, responsive and with the gore aesthetic they feel very satisfying. Movement is sharp and if you are a skilled player (unlike me) u might be able to do some awesome tricks. Game have a sequel, i haven't played it and unfortunally it is not available on GoG.
