These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Grid Warrior
Demonic Spiders: Thunder Towers, which summon a satellite drone. If said drone hovers over you, better whip out and fire your Anti-Air gun and take that drone out, because if you don't, the tower will make the drone zap you, doing very high damage AND stunning you for more deadly attacks to come!
The Solar Laser proves that Light Is Evil with that laser cannon. At higher levels, TWO hits from its Wave Motion Gun and you're history (if you didn't get many health ups).
