Okay, so here are the details.

Tokyo Martial Law and Tokyo Martial Law (HARD), two of the multiplayer co-op missions, have a wave of enemies, a Mission Update with a specific mini-boss enemy, and then a second wave of enemies.

During this second wave of enemies, there's a chance to hear the original 1954 roar over the radio, which signals the presence of a monster. We only have confirmation of the appearances of Godzilla and MechaGodzilla, but we've heard rumors of Mothra appearing as well (but Mothra is unlikely). The monsters have random spawns in Tokyo Bay, ranging from the middle of the map all the way to the corner. All they do is occasionally play the roar and walk in the water towards Tokyo. They are physical and can be attacked, but they do not fight back. Seeing Godzilla or MechaGodzilla will award a commemorative emblem with the Godzilla VS logo as well as the portrait of the respective monster.

There are also in-game challenges, such as using a certain weapon or using a certain aircraft in typical gameplay, but there's also a challenge that asks you to "observe a monster" in the Tokyo missions, which means getting one of those appearances. Completing that unlocks a challenge asking you to use an F-2A (one of the aircraft of choice of the Japan Air-Self Defense Force) and physically attack the monster. These challenges award certain in-game items like credits or research items, but you can also get more Godzilla VS emblems as well as nicknames (which act similarly to titles in other games).

As far as we can tell, this event lasts until August 3.
