Stage starts off with a Heavenly Hippoe and Gabriel (groups of 2) spawning. 2 more Heavenly Hippoe spawn around 10 seconds later, with Gabriel's continuing to spawn throughout this time, until the base is hit. Once you hit the base, Sunfish Jones and Angelic Slepnir spawn with a group of Gabriels, a couple of Gory and another Hippoe. The stage then goes into a pattern of spawning a few Gabriel's, 1-3, and a Gory for the rest of the fight. A group of 4 Hippoes spawn around 30 seconds after the base is hit, with the spawn rate of both Gory's and Gabriel's slowing down after this.
It helps a lot to have Artist Cat, as he is cheap, has high health, good DPS, and counters Angels.
Basically, just drop a couple Artists to stall the first few enemies while you build up your money. Then quickly use long-ranged units alongside your Artist Cats.
Try to kill the Angelic Sleipnir quick, as he can do lots of damage.
Eventually, the Angelic Gories will just stop spawning altogether. Then swarm Sunfish Jones with Artist Cat, and you should win soon.
Strategy 2 by HushT
Line up : Crazed Cat, Crazed Tank Cat, Artist/Ramen Cat, Paris, Dragon and or Crazed Dragon, A. Bahamut.
All you need to do is stall the first enemies to get your wallet up. Then start to spam Artist/Ramen along with Dragons and Paris. These should be good enough to kill everything until only Sunfish Jones is left. A. Bahamut can easy take him out.
Any massive damage dealers should speed this up.
- This level features only Angel Enemies, just like Red Alert features all Red Enemies, and Black Premonition features all Black Enemies.
