still plays well in 2008
it basically continues where Quake II finished, and is very similar to that game, obviously with better graphics and you get the chance to drive tanks, and fight alongside team-mates - the good news is you don;t have to command those team mates, and they can be useful if they're medics or technicians, replenishing your health/armour and improving your weapons.
there are a variety of enemies, with the most chilling factor being that they are manufactured from your former colleagues. as with Quake II, you get to see the whole grisly process of how they convert people, so the '18' rating is a necessity, but if you take it with the humour intended it's OK - though i did have to turn my head a couple of times about half-way through - those who've played it will know what i mean...
definitely a game any FPS fan should play.
play on second-hardest level for fast-paced action, or hardest level if you want those bosses to REALLY test you!
