Very fun game but also extremely sorrowful because of so many Miners and the cool technician Hendrix who die.
Graphics are not great and should certainly be improved but they don't look terrible either.
Excellent soundtrack and audio effects.
I like flamethrower because I think it's fun to burn the Guards and watch them run around until they die and if other enemies touch the fire, they will burn too. However, if you try this with the Mercenaries, they will keep attacking you until they die because of their strong resistance.
Hendrix mentions the Mercenaries appearing all over the complex killing Miners and Ultor Guards too but they don't kill Guards and only kill Miners so it looks like they are allies with the Guards. There are also no corpses of Guards when the Mercenaries start appearing. I think Hendrix should have said the Mercenaries were appearing all over working together with the Guards to defeat the Red Faction. It was mentioned that Ultor sent a message to the Mercenaries to fight the Red Faction.
I like how the Guards and Mercenaries have different weapons. The Guards are armed with pistols, assault rifles, shotguns, rocket launchers, sniper rifles, control batons, and submachine guns. The Mercenaries have precision rifles, heavy machine guns, rail drivers, fusion rocket launchers and flamethrowers.
Some multiplayer playable characters such as Hendrix, Eos, the Guard Commander and the Mercenary are only available on the PC version. It would be so cool if the PS2 version had all those playable characters.
The satchel charge is fun because it will stick on Guards and they will run around and panic and they will die when you detonate the explosive. This will not work with Mercenaries because of their heavy armor.
The Miners got killed so quickly which was so annoying to me.
I like how Mercenaries are a lot harder to fight than the Guards and more brutal too.
There certainly should be a remake.
