A number of multiplayer glitches have been reported to Sega's FPS on the Wii, The Conduit. Nintendo Everything reports that among the said glitches would be those concerning the "spawn under the map" issue. For their end, Sega has responded to those emails sent out voicing this problem.
Associate Producer Jaramiah Severns put out a statement to address this matter:
We have received a few emails from fans regarding multiplayer snags and I assure we're working hard to fix those issues. It's difficult to address "glitches" post-release, but we're working closely with Nintendo to come up with potential solutions.
Help's on the way guys. Hang on.
