Now I know where the DyingLight1 themes came from...

This is the most dismal and with least of integrality part of the series. Not a bad game, but consolish-low-scale and had none of preeminence in 2011.
Play only for the sake of great-sounding helicopters (sound even better than the FarCry1 copters!)

Gameplay:
combat mechanics [feels a bit raw and consolish] 7/10
combat logic: RETRO
atmosphere 4/10

Lore and setting [acquired some seriousness, but raw AF] 4/10
<Story>
Plot and characters/semiotics 5/10

Graphics [love the harpies unique design] 6/10

Sound work (play through Fusion2017 with OpenAL option) 9/10
Sound design & music [good footsteps, lack of other goodies] 7/10

.
HINT: use improvised tools in the final boss battle.

"6/10"

After so many years
I still don't like it

Awful experience, extremely boring and annyoing as hell

yes

The WHOLE game is PURE fun and CRAZY!! You WILL Love Sam!!!

Great game. Slaughtering Aliens, saving the Planet. What could be more fun. It is actually Serious. When hordes of Aliens are chasing you to rip you apart.

A high point in the series. Grab this game when it goes on sale. The Serious Sam franchise goes on sale pretty frequently.
