Godzilla: Daikaiju Battle Royale is a fan-made flash game made by Alex Merdich.
In the year 2XXX, the Xiliens have declared war on Earth for the second time and now have more monsters than before. The commander tells Earth to either surrender or be destroyed. The intro then goes on to either:
Say that the player's monster broke free from the Antarctic and the fate of Earth now lies in it's hands. (Earth Defenders only)
Say that Earth had no intentions of surrendering, knowing that they have defended Earth against Aliens in the past, and send the player's monster to defend Earth. (GDF only)
Say that conquering Earth was hard for the Xiliens in the past, but the player's monster shows promise to achieve victory. They will test this monster and then send it to Earth to take over the planet. (Aliens only)
Later, the player's monster either attacks (Earth Defenders or GDF) or defends (Aliens) the Xillien's Earth Base in World Children's Land. After the player wins, the Xilliens either send the player's monster to Planet X to face their trump card (Earth Defenders or GDF) or send them to fight Godzilla in Tokyo (Aliens). The ending tells us that the player's monster saved the Earth (Earth Defenders or GDF) or took over the Earth for the Xilliens (Aliens).
Battle Mode is where 1 or 2 players can choose two monsters and battle against each other. The stats for Physical Attacks, Special Attacks, and Power Regeneration can be modified, with the default being 3, 1 being the lowest, and 5 being the highest.
The game has a total of 64 monsters (Counting the different versions and transformations), all of which are playable, although most have to be unlocked. In addition, some monsters can transform into different ones, either at will at the cost of some energy, or after a certain amount of life has been depleted and with enough energy. The playable characters are:
All stages except for Planet X have a day, noon, and night option in Battle Mode.

There are certain mechanics to the gameplay that will usually change the death of an enemy monster.
If Godzilla 1954 is killed in battle, he will emit the death cry that he made in the original film before falling onto his back.
If Mothra Larva is killed by a beam, an adult Mothra will fly in and attack the player. This ONLY works in Arcade Mode.
Minya has different animations for each of his roars. If you defeat Gabara, the victory screen will show Minya dancing and shouting "Yayayaya!". Also, if you defeat Kumonga, the victory screen will show Minya dancing and shouting "How do you like that, weirdo?!". If he is defeated in battle, he will run away.
If King Ghidorah 1991 is killed, he will fall on his back and roar. If he is hit by a beam attack during this, his middle head will fly off.
If M.O.G.U.E.R.A. is killed with a beam attack, it will charge at the enemy and explode on contact. If it is defeated by a melee attack, it's right arm will be blown off while M.O.G.U.E.R.A collapses.
Godzilla 2002's victory animation has him getting struck by lightning, much like how he does during his intro at the start of Godzilla Against MechaGodzilla. Additionally, when being defeated, Godzilla roars, slumps forward, and collapses.
Godzilla 2002's alternate costume is his 2003 incarnation, including his battle scar from when he was injured by Kiryu's Absolute Zero Cannon. Additionally, both incarnations possess different Heat Ray charging animations.
Once the arcade mode is completed while playing as Godzilla 1954, the end message reads "In the end, the people of Planet X could not defeat the monster. They had no choice but to return it to Earth and admit defeat. The Earth, and the entire galaxy, was safe once again thanks to Godzilla... or is it?" as a picture of Godzilla 1954 pops up over the Earth.
