Beachhead Invasion

Beachhead Invasion (なぎさの猛攻) is the first stage in Marine Ministry.

Battleground

• Director Kurosawah spawns at the start of the battle.
• The enemy base, a Doge Base, spawns after 0.07 seconds^2f.
• When the enemy base reaches 99, 98, 97, and 96% HP, Bore, Nimoy Bore, Razorback, and Boraphim spawn as bosses, respectively.

Strategy

Really, the only thing you need to do is lure every single boss, then kill it, then trigger the next boss with Bomber. Do not use any cats with above 30,000 HP or with Survive during the first 4 bosses.
Start by luring Kurosawah, then perma-freeze him with Bombercat. Eventually, Kurosawah will die without the Doge Base being triggered. When Kurosawah dies, allow your cats to die by the wave, then send a Bombercat to chip at the base until the Bore spawns.
When Bore spawns, lure it, then perma-freeze with iCat. Eventually, Bore should die too, and you can allow your cats to get killed by the wave. Once again, chip with Bomber until Nimoy spawns.
When Nimoy spawns, lure him, then stack Psychocats while using other hard-hitting cats (below the hp threshold though) to chip at him. By now, you should know the drill.
Repeat this process with Razorback.
When Boraphim spawns, lure it, but go all-out this time. Use your high-DPS cats like Bahamut to shred Boraphim to pieces. Talented Sanzo and Juliet can help for stalling Boraphim. When Boraphim dies, send Octopus and wait for the victory.
