Dead Rising Deluxe Remaster

Special forces soldiers are a new type of human enemy exclusive to the Overtime game mode (4th day and beyond). You get 5K PP for killing each one. They also appear in Infinity Mode on the 4th day.

Like in the original game, the best way to dispose quickly of the special forces soldiers melee-wise is the Disembowel special move, which is done by holding and then pressing while facing them. You unlock this special move around level 40-45, and it instantly kills any soldier you may encounter.

You can also kill them instantly with the Face Crusher special move, unlocked at around levels 36-40. Again, perform this move by holding and then pressing while behind one of them.

Anyways, if you are at least level 45, you can hold and then mash while close to one special forces soldier in order to do one special move or the another.

However, soldiers can stunlock you by shooting repeteadly, so be clever about closing distances with them and have several food items just in case. Try to approach lone soldiers first and kill them quickly.

P.S: you can unlock the full list of Frank's special moves by picking up the magazine in the gym Flexin' in Al Fresca Plaza. This allows you to perform every special move even though you are low-level and haven't unlocked them yet!

After completing all cases, the special forces will arrive at 12 am on Sep 22. They will be scattered all over the mall and usually are in pairs of 2. Get one of their machine guns and shoot the special forces until they get knocked back / flinch and keep shooting them until they do it a second time. After that, switch to your hands and finish them off, as they should have low enough health. Just run around doing that until you get all 30 for the Achievement.
