It was on sale during the Spooky Sale , that ' s when I grabbed it . <| sep |> My favourite thing about Merson is how he is so inconsistent with his opinions . Last week sky did a can united still win the league article and Mersons contribution was I always said it would be very hard for them to get top 4 . If you look at his predictions from August and September he predicts them coming 2 nd or 3 rd every time . He just makes it up as he goes along and I find it funny more than annoying now . <| sep |> Only level 17 so far , but I go with Heavy Weapons Training , Medic Training and Ammo Vest . At the start I always use Melee Expert to conserve ammo but change it to Medic Training after a couple of waves . For weapons I run M 79 , Crossbow and Medic SMG during the waves . I ' ve found this to be quite successful and to me , insanely fun as well having such variety in the weapons .
