Extra details:
Slayers and Survivors can both be played in a team mode. This allows free for all and 2v2.
Characters must be bought through exchange points instead of unlocked, except for Chris BSAA and Sheva BSAA. The total price of all the characters is 134,000. No new characters or stages are in this DLC.
If an enemy player is grabbed by a Majini or other creature, you can approach them and use the normal context sensitive action to free them. However, this attack will damage both the enemy player and the Majini or whatever creature has grabbed them. It will both release and harm the player.
Players can be frozen by Nitrogen Rounds. The freezing time is 5 seconds, but if X or A is tapped recovery will happen more quickly. Other players can attack you while you are frozen, including hand to hand, but you will not be shattered by the attack. Nitrogen Rounds will not harm players on the same team.
In Slayers and Survivors games you normally cannot give weapons to other players. However, in a team survivors match you will be able to hand the M3, H&K PSG-1, S&W M500, Grenade Launcher and Rocket Launcher to a partner. You can give ammo to a team member as long as they have a free slot or an existing stack of the same ammo that can hold the ammo up to the slot maximum. You can swap items when your inventories are full.

Extra Info Continued and Tips
When a player is killed or dies in a Survivors match, they will drop a weapon on the spot where they fell. The drop is chosen randomly from the inventory, but it cannot be the default firearm. The dropped weapon is always fully reloaded, and a respawning player will always have a fully loaded default weapon. A dropped weapon will only appear for collection once a body has been removed from play. I imagine that means when the body melts into the ground like a normal Majini.
Proximity Mines take a few moments to arm, and are indicated by a flashing red beam so as to not be confused with an item on the ground. They can be detonated by bullets and splash damage from grenades or oil drums. Majini can still trigger their explosion. Enemy players can see Proximity mines and detonate them with gunfire, so they should be placed at tactical locations such as at the top of climbable ledges or ladders, or at the base of jumps and drops, around sharp corners, behind doors, below windows, etc...
Injury from explosions will generally cause knockdowns. If your character shields themselves from the blast, they will take no damage. Explosions in RE5 have a small blast radius, so training to have proper aiming will be helpful.
Enemies will pursue a player unless and until a nearer player diverts their attention and becomes their new target. If you see Majini or other enemies gathered in an area, chances are a player is nearby attracting their attention. You can also lead enemies and mini bosses to other players, providing for a neat and unique strategy.
ery. The very beginning of the level where Chris and Sheva are shooting off the back of the boat took me forever, because there are about four guys with crossbows that you have to take out extremely fast, or else you're
