The funniest thing I heard a helghast troop say in the first KZ game was "What the hell?" Every time I caught a small group of two or four helghasts I would throw a grenade to clean them from the premisis. Then I'd hear "What?" "What is that?" "Grenade!" "Grenade Take Cover!" or "What the hell?" and then they'd be flying like birds and then drop like a brick to someone's head on the ground. I would die of laughter every time they came out with "What the hell?" after they saw a grenade roll like a marble towards them and then they'd scream when they die. It's all too funny. The things the helghast say in KZ 1 makes every other game less funny. It's the funniest game I have ever played. You could shoot them with a silenced weapon and they'd wounder where it came from. There's a glitch with the sniper rifle in KZ 1 where every time you fire, the sniper does not make a sound and therefore renders you impossible to be tracked down while quietly sniping. But the glitch won't always occur so don't expect yourself to be lucky.
