Serious Sam 2

Serious Sam 2 is Croteam's 2005 follow-up to The First Encounter and The Second Encounter, leaning further into colour, oddball enemy design, and arcade-style chaos rather than the original duology's sun-bleaked ruins.

The campaign sends Sam Stone across 40+ levels in seven distinct biomes — jungles, swamps, tundra, futuristic cities — to bring down the recurring antagonist Mental. Forty-five enemy types include bomb-tossing clowns, windup rhinos, zombie stockbrokers, and the series-signature beheaded kamikazes screaming toward you in waves.

The weapon set keeps the classics — shotgun, minigun, rocket launcher, cannon — and adds new pieces like the Klodovik, plus secondary-fire grenade tosses for crowd control. Turrets and mountable vehicles, including some rideable animals, break up the run-and-gun rhythm.

Co-op and deathmatch support up to 16 players across all 42 campaign levels. Native NPC tribes occasionally fight alongside you, giving the single-player campaign brief stretches of incidental co-op.
