No confirmed fix yet. Players suggest: Try doing a custom battle on Monster Island on Medium/Hard and destroying the stone towers (NOT the ones surrounding the lava pit)
No confirmed fix yet. Players suggest: This was the solution thank you
Suggested fix (unconfirmed): Set the CPU difficulty to "Easy" and play aggressively. Use Godzilla 2000's sweeping tail attacks to stun enemies, or spam King Ghidorah's dive bomb.
Suggested fix (unconfirmed): Hold the crouch button, then press the jump button.
Suggested fix (unconfirmed): Go to the online game menu and click "invite a friend" to play with up to four friends. Note that there is currently no 4-player matchmaking.
No confirmed fix yet. Players suggest: to be fair, once you get everybody there isnt much else to do besides grinding the gallery, enjoy the time while you have stuff to do in the game while it's there, I got a feeling it'll be a while until we get anything…
Suggested fix (unconfirmed): Change the AI difficulty setting to "easy" in the options menu. Alternatively, select Monster Island and repeatedly throw enemies into the lava while edge-guarding the volcano.
No confirmed fix yet. Players suggest: Would be easy enough to put Charizards model over King Ghidorah or something and change his beam to flame breath.
Suggested fix (unconfirmed): Complete four battles in survival mode and then die on the next one. The unlock triggers at the end of the run.
Did you quit Survival mode after you won the four matches? You actually have to lose the survival game in order for these challenges to count, you can't just exit the mode through the pause menu.
I've unlocked all the Kaiju and Ill let you know. Destroyah, Mech-Ghi, and Mecha-Godzilla all have about three or four unlock challenges/research you have to do.
No confirmed fix yet. Players suggest: It should've worked for me
Suggested fix (unconfirmed): Stay in the air using building-throwing tactics, or block ground attacks until the enemy finishes their moves before counterattacking. Use Rodan's beam attack whenever possible since it deals heavy damage.
Suggested fix (unconfirmed): Select a map project in the G-force Lab and complete adventure matches to progress your research. Switch to a new map project after each finished research until you reach 8/8 to unlock the final research project for Rodan.
