Raiding

Raiding is attacking a player's base by yourself or a group of people. It usually costs resources for both the attacker and the victim. Generally somebody raids because they want to steal possible money from money printers or stop you from building in that spot.

Tactics
Go for turrets, they do the most consistent damage before players and always stand still, so throw a few bombs at them.

If they are elevated and you cannot reach them then try to dodge all you can and go for your second most important target, beds and players(Generally you want to go for beds first). Without beds the enemy player can't respawn there and have to spawn in a random place in a biome. Use this to your advantage as when the bed is destroyed every time you kill that player they have to spawn in a random place in a selective biome and they have to run to you, giving you more time to destroy their base then you'll wanna destroy there base by spamming bombs at the walls, the spikes, everything. Unless you just wanna get rid of their bed turrets and loot their money printers then you can skip this option.
