The Rebel VTOL is the first boss of Metal Slug: 1st Mission. It is fought at the end of Mission 0 (Emergency Mobilization).
Boss Strategy[]
The Rebel VTOL slowly hovers around the screen. Once it stops moving, the VTOL tilts its Gatling guns on one side and starts firing to the ground until the VTOL's guns tilt to the other side. A Machine Gun crate and a Bomb crate are hidden in the arena.
The Power Generators from Metal Slug: 2nd Mission function similar to the Rebel VTOL.
