The year is 2024, and giant robots called the MegaMechs attack the world. No one knows where they came from or why. Only that they seek to destroy the Earth. With all leading nations destroyed, its up to a small restistance group to fight back against the threat.
Tropes associated with Mechstermination Forces are:
- All Your Base Are Belong to Us: At one point. You've exterminated all MegaMechs. You are instructed to take a well earned night's rest.
- Attack Its Weak Point: All bosses are this, but with a catch. Red cores must be smashed, while yellow cores can be shot down.
- Bandage Mummy: One of the soldiers at the camp.
- Colossus Climb: Several of the MegaMechs require climbing up the outside and/or inside of them to reach their respective weak points.
- Convection, Schmonvection: One of the MegaMechs is fought in a live vulcano. If the player character falls into it, it will just deal one heart of damage as usual. And a platform will rise out of it.
- The Cuckoolander Was Right: See also Mythology Gag.
- Damn You, Muscle Memory!: Try playing an older boss within the simulator. You'll get your health, and your new weapons but lose your double jump and climbing skills.
- Double Jump: With the boost boots.
- Combining Mecha: The TriMechalon 2000 is made of of a robot crab, bird, and robot, which combines into a robo-dog. The Final Boss is this with every boss.
- Kill It with Fire: A flamethrower can be purchased as an extra weapon early on. While it has short range, it does decent damage and is one of the best defensive weapons for destroying yellow bullets.
- It's Personal: The broke my coffee table.
- Mythology Gag: Several billboards for Gunman Clive 2 can be seen in the background while one of the MegaMechs is an upgraded version of the final boss from that game as well. Also much like Gunman Clive 2, the final boss is a mech controlled by a duck.
- Miles Gloriosus: One of the soldiers in the camp is a Bandage Mummy who claims he is the best soldier there, fought all the Mechs you did, but without the equipment, but he just keeps breaking all of his bones.
- Pajama-Clad Hero: In the All Your Base level.
- Punny Name: If the MegaMech doesn't have a Shout-Out as a name, then it will most likely have one of these, like the giant snail like boss Mechscargot.
- Secret Character: If you own Gunman Clive HD Collection on Switch, you can unlock Gunman Clive himself as a fifth playable character.
- Sequential Boss: Every boss has at least a second form, either it transforms, or it loses bits of its original design and is determined to still smush you.
- Tricked-Out Gloves: The magnetic gloves that allow you to Colossus Climb
