Yeah, I was goofing off, it was kind of obvious that I knew I was in the blast radius, but I also needed a way to respawn so that I would have lower damage and could do more. Also, lol Yubel you clicked modify instead of reply. Oh well.
And yeah, Snake's recovery with the C4 detonation on himself and then using the Cypher is nifty. Hypothetically you could do the same effect with a grenade, but the only way I know how to do what you are describing is to drop a grenade on the ground, pick it up, and then somehow end up near the bottom and have it explode. Otherwise you would have to catch a grenade thrown at you by your opponent that was yours or something. It is hard to say without seeing.
