Title screen

Shooting a swarm of alien ships

Targeting a red stinger missile towards a group of larger enemies

The Air Tank boss - this is the first boss (and obviously the easiest one to defeat) in the game. Just shoot at the gate to open it and launch a stinger into the opening to destroy!

Disarming one of the game's titular Drones

Successfully disarming a Drone results in a message of praise from an unnamed officer who nicknames you "Sparky".

Onto the second level, which takes place in a desert. This is the Gemini boss - you need to launch several stingers towards the left and right sides in order to destroy it.

The Level 3 boss - shoot at the plasma and launch a stinger into the centre to take this bad boy down

Battling the "Spidey" boss over a river - shoot at the shields to rotate them until an opening is created for a stinger to be launched into

The Snake boss - this is basically like the Air Tank boss from level 1, except there's six of them!

The Drones on levels 5 and 6 have larger enemies escorting them, so it's harder to make an opening for a blue probe to be launched at the Drone.

The Bomber boss - this is just like the boss from level 3, but this time the plasma is a moving wall!
