Serious Sam HD The First Encounter (2001)- PC
Those who’ve played any game from the Serious Sam series, know exactly why one of them is on my list. Completing a play through on single-player mode is a magnificent feat, especially if finished on the “Mental” difficulty level. When played with almost twenty people on a server, with everyone attacking a variety of gargantuan monsters with a plethora of heavy duty weapons, it’s an astonishing amount of fun.
Not partial to traditional gore? Serious Sam had the option to change the blood of enemies to hippie flowers, candy, or liquid rainbows for more lighthearted players. Pretty sick, right?
