S0u7Eat3R_333 there is,but not at the end,it's the Barret,a mag-fed semi-auto sniper-rifle that can triple-kill(or more) in 1 shot,the mag has 10 bullets and the chainsaw-glitch works with it as well,so it totally kicks ass!
lol!choose a shotgun,go to irish safehouse,aim at their chest,I got things like this:mission shots:3 Mission Hits:6 Mission Accuracy:200 Mission Kills:3
for dummies who don't understand level 10:It's pure logic,translated to english it would look like:
1.G is true
2.if M is true,G is true,so A is true
3.M is true
4.(guess,I gave a huge hint)
5.if M and A are true,E is false
6.therefore E is false(not E)
7.if O and V are true,E is false or R is true and vice versa
8.(O is true)
