Choo-Choo Charles is a horror game in which you have to confront a walking train with spider legs. It would seem that it can be frightening in such a situation, but when this creature tries to eat the protagonist, it will no longer be fun. The user is almost completely unarmed, so you can escape with the most thoughtful tactics. Protagonist is an experienced monster hunter, but even he is faced with such a phenomenon for the first time. Recently, he received a call from a settlement heavily dependent on the railroad. Entire trains began to disappear or derail in mysterious ways. Some kind of creature resembling an old-style steam locomotive attacks other trains and eats its drivers.
