Use the Slug Dodge (Jump + Down) to gain 1.5s of invulnerability inside tanks. Take the underwater submarine path in Metal Slug 3 Mission 3 for heavy weapon drops.
Metal Slug X is the ultra-refined 1999 revision of Metal Slug 2, eliminating slowdown, introducing new weapons (Enemy Chaser, Iron Lizard, Drop Shot), and reorganizing enemy placements for peak arcade pacing.

Rapidly tapping Crouch immediately after a knife slash cancels the recovery animation, allowing three slashes per second.
