Half-Life: Opposing Force

I especially like the alien weapons like the Barnacle, the pea shooter, and the electric ant.

The squad mechanics are fun to use, and the new enemies are quite challenging but I never found them impossible.

The expansion also introduces some very cool lore elements that build naturally on the original story.

One word~ COOL, everything about this expansion is COOL, from the enemy design to the weapon, amazing experience, but you better play on normal difficulty for more enjoyable experience, or you want a true HECU experience then tried hard difficulty~

The addition to the lore that this game offered was also very welcoming, it was a lenghty & solid expansion that I would play it all over again with different mods, the multiplayer mode is also worth checking out for all of this and the CTF mode.

Starting out, the expansion pack already throws a decently sized roster of weapons that you can use your way, which honestly was fantastic, because most encounters with an enemy left you with an incredible amount of choices to how you want to go about it.
