We've finally found our target. Apparently those three obelisks on the horizon are attached to some crazy teleportation tech, and each one is linked to a fourth signal high above us.
Whatever's up there is what we need to take out.
Santiago says he can get us there by bypassing the security on one of the obelisk's platforms. Trouble is, we don't know what'll be waiting for us, and not everyone here's combat ready. So we're going to take the diplomatic approach and make our mysterious hosts a present.
The leaders don't want to risk spoiling the surprise, so we're discretely building it in pieces. The whole bomb won't even be assembled until the minute the operation starts. Our captors won't know what hit them.
