How to unlock the All Growed Up achievement in PROTOTYPE 2 - Definitive Guide
1) You need to get to level 23 worth 2.530.000 EP (evolution points)
2) You need to get
3) You need to get all collectibles of every type and complete all Blacknet Missions
Story missions give by far the most EP. However you won't have enough of them in one game to get past level 18 or so. With a New Game+ you can quickly get the remaining EP in the beginning of the Red Zone; Story missions there give about 45.000 EP
If you're just missing little bits of EP you can of course go for the collectibles again. They are worth 1500 EP each. Every little bit helps but if they are out of your way just ignore them.
You can track your EP and level through the Heller menu option after pressing
The game has a NG+ and all of your progress will carry over to the "new" save file.
I would recommend playing the game on easy mode first, getting all of the collectibles, and then just rushing in hard mode for the other achievement. The second playthrough shouldn't be longer than 5 hours while the first will be around double that.
This is the most time consuming trophy in the game. You will need a total of 2.530.000 XP and the maximum level is evolution level 23.
Always try to consume enemies with the symbol above their head. This will reward you thousands of fast and easy XP. Also pay attention on the bonus targets during main plot missions. The bonuses are fairly easy to get and if you messed up you can still reload the checkpoint and try again. The main plot missions will give you the majority of XP though. After finishing all main and side missions and getting all of the collectibles you should be somewhere between level 18-20.
I recommend to do two playthroughs. Do the first one on easy and get all of the collectibles. Then you create a New Game+ on hard difficulty and get the remaining XP just from the main plot missions. All of your upgrades and XP carry over into your New Game+.
You will gain EP(xp) mostly from doing Missions and from gathering Collectibles. You will also get some for smaller things such as consuming those with a DNA symbol or completing bonus challenges. You will need to do 2 playthroughs to completely level Heller up.
Eat monsters with the DNA icon at the top (bio-bomb, pack leader, your blades, hammer arms, etc. are improved)
And you also need to get to lvl 23 (that’s what you need to unlock all abilities)
You won't be able to do this in 1 playthrough. Start New Game+ on easy difficulty (if your first playthrough is on Hard) and skip all the story cutscenes. In an hour and a half of playing you will reach lvl 23
Personal experience has shown that in this case the trophy is achieved in the Red Zone on a mission where you need to absorb an FBI agent who knows where GG’s daughter is or near her. This, of course, will not take an hour and a half, but everyone can handle it and you can handle it.
