Ok, im late to the party, but here it goes-
A lot of hidden things have been discussed or added in my character guides but will add some stuff here.
These are all before update fixes, that have been posted today in the (Whats-Up)
Sire-If you have a MKS Lancer and a Sire is right on you. Just rev the Lancer and it will block the Sire from Downing you. Now you need to be facing them for this to happen.
Grenades- You can actually have the game keep your grenades after use. On the last grenade you have, just pick up a DBNO enemie by pressing X to start the meatsheild mechanic. After this, press UP on the D-Pad to plant a grenade on their head and kick them. If you survive this, as in not blowing yourself up. You will see your grenades as being empty instead of being removed completely.
Del- If you have Del’s Legendary Card unlocked. You can Stim MAX OUT by capturing a open TAP and repairing it while capturing it. Sounds weird, but just pull out the repair tool and repair the Hollogram Tap as its being captured.
Leveling- Your Character, any for that matter, will do more Mele Damage the Higher they level up. So a Lvl 18 whoever can do more Mele damage than an Emile on low level.
Pilfer ammo-Pilfer Ammo will completely regin the Mace in Horde. It will give you full ammo. As the Pilfer works buy how many rounds can be shot from a gun. This is why the Claw will get a 100 rounds from a single pilfer, compared to a lancer only getting like 20.
Sire Teleporting- If you have a Sire get near the Fabricator just run, as it will suddenly disappear and then reappear right on you. However, if playing on DAM. If the Fabricator is close to the Wall but with an Open back, the Sire can Teleport right off the Map. Guess he’s going home.
There are more, but super busy today so have fun with these until they get patched.
