UndyingNephalim has been doing a lot more work on his fangame "Star Fox: Event Horizon" in recent months after publicly taking a break a while back. Every month or so there's some new video or experimental game mode.
Above, we have the most recent video, in which Fox and Krystal take to a hoverbike on the deserts of Sauria to fight off a bunch of SharpClaws and some mysterious scorpion enemies. It's particularly interesting because a land speeder is not at all what the Freespace engine is designed for.
Then, there was a fairly recent video of UndyingNephalim's interpretation of the Sector X incident from Star Fox 64. It does something I think is lacking in a lot of these open space, fly anywhere games: giving you something interesting to fly around. In this case, you arrive at the secret base as it is exploding, giving you new and interesting space "terrain" to fly around as you fight enemies and the boss.
I'm trying to post every day again. Please forgive me for posting stuff you've already seen. I'll try and mix older stuff with newer things. And hey, you might just see something you missed!
