Raiden sneaking off from the sneaking group is fine! He'll find a lot of incredibly advanced technology, way more state-of-the-art than what the Initiative has. Among this equipment will be DNA decoders, swank coffee makers, chalkboards with uncreative math jokes written on them, schematics involving the alteration of DNA, someone's stash of chili peppers, and theoretical illustrations of outlandish human bodies. Raiden is free to dispense these findings among the populace as he will after the mission is complete.
