Content warning: This game features descriptions of war, death, gun violence, and drug/alcohol abuse. There are no graphic images in this game.
There are a few casual mentions of suicide in conversation between political adversaries (e.g. a character saying "If you want to commit suicide, there are better ways to do it" to reject a plan you proposed to them).
Additionally, there's a hard-to-reach path where the player becomes the new dictator of the country, and if specific conditions are met, the player is given the option to commit suicide in a manner similar to Adolf Hitler. I hope this is considered within acceptability for the game's dark themes, and if it helps, this specific path is unlikely to be seen by the majority of players except people who specifically try to get this outcome.
That said, I'll gladly withdraw my submission if the mods feel this crosses a line. Thanks!
