Surrounded on all Sides
Send 2,000 enemies to your opponent's map.
To send enemies to your opponent's map, you must kill enemies in rapid succession to create a kill-combo chain. Once you have a combo chain going, at anytime, you can stop moving at tap
to end your chain and send enemies to your opponent's map based on what your kill-chain combo number was. You can also wait until you have reached a Killer Combo (30 kills) to have the game automatically send those 30 enemies to your opponent.
For this trophy, you will need to do some grinding, though not very much.
All you need to do is use
or Killer Combos to send enemies to your opponent. Just keep killing and tapping
or reach a Killer Combo un til you have sent over 2000 total enemies. You do not have to do this in one match, and are almost guaranteed to not be able to do this in one match.
To check your progress on this, you can either go to the "Records" section in the main menu and scroll to the right, or you can also enter the "Dog Tags" section and scroll to find the "Mighty Spammer" title. When you achieve this trophy, you will also max out this title.
Take the Stage
Defeat your opponent and achieve victory in 3 stages.
This trophy is pretty straight-forward, and if you have a booster, can be done in less than 20 minutes.
All you have to do is defeat your opponent at least once on all 3 of the main stages that the game already came with. Keep in mind that winning on the DLC stages purchased from the PlayStation Store do not count towards this trophy.
The 3 main stages are URBAN CHAOS, STEEL BEAST & MINING THE DEPTHS
Achieve a 30-combo chain.
Combo chains can be achieved by killing enemies in rapid succession. You don't have to kill them one right after another, as the game gives you a good few seconds to achieve your next kill before the combo chain ends. You'll notice that if you have a combo chain in progress and you don't kill an enemy for a few seconds, your combo number will begin to flash, flashing faster and faster as it runs out of time.
For this trophy, you need to kill 30 enemies, at which point your combo will automatically end itself and send 30 enemies to your opponents map.
Do not press
at any time during your combo, otherwise you will end the combo manually and send enemies to your opponent based on whatever your combo number was.
This trophy can be earned while playing on the DLC extra stages besides Urban Chaos, Steel Beast and Mining the Depths
You are S.O.L.
Defeat your opponent 10 times with enemies you sent.
For this trophy, you must build up a kill-chain in order to send enemies to your opponent's map. Achieving higher combo chains sends tougher enemies to your opponent. The more you send over, the better your chances of killing your opponent with those sent enemies.
For this trophy, your opponent must be killed by an enemy. They cant be killed by any environmental object such as red flammable barrels. I do not know, however, if it does not count if your opponent is killed by an enemy that spawns on your opponents map, but is not sent by you. Anytime my opponent died by an enemy, it was because of an enemy I sent.

Kill or be Killed
Win while in the dying state.
This trophy is so much easier when playing with a booster.
The dying state is when you are lying on the ground on your back, screen somewhat blacked out around the edges and tinted red in the middle. There is also a "recovery" bar in the middle that fills from left to right. This is a timer, telling you how long until you are able to get back up and resume the fight on your feet. You can kill enemies with the gun you had equipped before you went down while in this state, but be cautioned, because if you get damaged once during this state, you die instantly.
WHEN PLAYING WITH A BOOSTER: as soon as the match starts, both you and your opponent throw a hand grenade on the ground and then both stand on top of the grenade to have you enter the dying state. all your opponent has to do is get hit by an enemy while your still in the dying state. You, however must avoid being hit by an enemy or else you will die. Be sure to equip a strong gun before entering the dying state, such as a shotgun, because you cannot switch weapons once dying.
WHEN PLAYING WITH STRANGERS: survive as long as you can until your opponent enters the dying state. you must then enter the dying state too, and hope that you do not get injured again, while your opponent does get injured again, before recovering. This may take many matches, as you probably won't have that many opponents enter the dying state. If you still don't have a booster for this, then keep finding matches and hope to get lucky.
