Giant enemy crab! I think this might be the first Metal Slug Rampage flash I've ever seen that wasn't a game. You really did have a story too. This was never a silly game to begin with. I just loved all the fine details. The sprite work was always great with this franchise.
That's probably why Tom Fulp liked it so much! I could hear Rina-chan's voice. She is in everything nowadays. Zombies are always cool. It could have been a little longer though.
