Really great game
Excellent game, great concept of having to hold territories for a certain amount of time to gain resources. 10/10!!
Just finished the story mode, saw that lots of guys having difficulty with worm boss, my tip would be to buy one of the rocket launchers, either will do (i used the cheaper one) and that way you can all those annoying little critters he spawns in one shot, no matter how fast they come at you (for this to work you need high gunsmithing, speed and armour)
Good Luck! :D
