2 new videos from the site that brought us the MP gameplay. Be warned, the videos show new enemy types (Stalker & Bloater), a lot of different settings, new characters and some cutscenes. It's SP gameplay only:
WARNING, the link ending in '58' is the same video from this thread which supposedly shows some pretty huge spoilers, in which the people who watched said they wished they hadn't.
The reason I post this is because OP didn't exactly make it clear that some will consider these HUGE spoilers.
I haven't watched the video so I can't comment on it's content.
Also Idk what the other video is. Is it more multiplayer or is it new singleplayer?
