Classic survival horror! |
The tasks are fairly straight forward and low in skill requirement, including escaping on all 3 lunar landers within the level during one game, killing a space monkey with a fire trap and Pack-A-Punching a weapon before Round 8.
The "They are going THROUGH!" trophy, awarded for killing at least 5 zombies with 1 Gersh Device, will require you to obtain the Gersh Device via the Mystery box, which, as always, is completely dependant upon luck, but if you follow through with basic strategies of zombies mode in solo play, you can easily get through enough rounds to be able to get the Gersh Device and fulfil the requirements of the trophy with relative ease.
In theory, you can actually unlock every single trophy in one game, and it isn't too demanding to juggle them around and create an order, though you will need to make sure you have a Pack-A-Punched weapon before Round 8 if you want to attempt all the trophies in a single run. That's just an emphasis of how easy this package is though.
Most important to note, you can unlock all 4 trophies in solo play and therefore don't have to rely on anybody else to complete the package.
