Garry’s Mod is a sandbox mod for the Source Engine. Unlike normal games there aren't any predefined aims or goals. Players are given tools and are left to entertain themselves. The player is in a world where objects can be created and destroyed on demand. Where people can be created and destroyed with the click of a mouse. A world made for him. A world he made.
The poor counter-terrorist fell of a helicopter when he got shot by his so called friend. Now he is in the water and his bloody wound attracts Ichthyosaurs.
Poor fella won't stand a chance.
Unless Gordon Freeman teleports somehow and kill it with his so-called weapon, the Crowbar.
Gordon is too busy fighting headcrabs and zombies at the moment.
And I don't think even Gordon can survive in here, these waters are full of Ickys.
