Copy-Cats
Now, don't get me wrong... I LOVED Red Faction... I've beaten it several times and I just love it... But I have one major quirk with it: Red Faction copies Half-Life in several aspects...
The aliens: Capek's Creatures / Headcrabs and Alien Grunts
The Army: Masako's Marines / Grunts on radio
The story
The character: Cousins?
The HUD/weapon choosing system
The environmental protection suit
etc. etc. etc. (If you don't see what I'm talking about, lemme know, I will explain)
Another few points:
A) H-L is the greatest game ever
B) Geo-mod in RF is so wicked cool!
C) The guards in RF need to take Focusyn... They can't even stand still for one frame, geez!
D) The man in the suit in H-L = VERY good idea for games, added a wonderful little mystery and unexpected ending!!!
