Medicalat

An Indie Game from 2002, Medicalat is a three-level side-scrolling Shoot Em Up where a space nurse and her personal Kill Sat in form of a huge syringe take on endless waves of enemies in the veins of a person to defeat The Virus who infects everything and everyone. A good game to fill pauses at work.

Tropes:

 * Charged Attack: Collection variety. You absorb enemies or their bullets and load the Kill Sat syringe. This makes its spread shot wider and also fuels the Wave Motion Gun.
 * Chekhov's Gunman: The other nurse appears as jus another enemy first, but returns as a boss later.
 * Cute Bruiser: The player's nurse.
 * Cute Witch: One of the enemy types. Some come with a warning.
 * Elite Mooks: Cyber sharks. Wave Motion Guns come late in the game.
 * Everything Is Even Worse With Sharks: Rocket-powered cyber sharks.
 * Excuse Plot: See the introduction line.
 * Explosive Overclocking: Overcharging your weapon results in an explosive discharge, costing you all power and a health point.
 * Giant Melon: The first boss.
 * Hollywood Healing: Eat a red pill to fill up one health point.
 * Kill Sat: Looks like a huge syringe and travels with you. It also is your Wave Motion Gun.
 * Mega Neko: The second boss is a giant cat-like balloon with a scorpion tail.
 * Mind Control: The other nurse is under this.
 * Moe Anthropomorphism: Cute Witches, devils and of course the two nurses.
 * Mooks: Lots of them, from red blood cell and pumpkins to devils, cyber sharks and Cute Witches.
 * Power Up: Three different pill types exist - red pills heal health, green pills charge the Kill Sat up and yellow pills can convert energy into health.
 * Redshirt Army: Red blood cells and pumpkins do nothing but getting killed. On hard mode, pumpkins can fire back.
 * Rule of Cool
 * Shoot Em Up
 * Sinister Geometry: The third boss fight is again against the other nurse who upon defeat gets trapped in a crystal. Said crystal can fire spheres firing other spheres and diamonds that (on hard mode) explode when destroyed.
 * Small Girl Big Gun
 * Spread Shot: Your syringe Kill Sat and most enemies.
 * The Virus: The final boss.
 * Wave Motion Gun: Everyone! The player character has it, the other nurse has it, there are enemies whose sole attack is this and every boss has a variation.
