No one care but heres a strat that i really like.
As you hear your friend presses E(beep beep beep beeeeeep) you then wait a second then press E. After the tank explodes it will scatter the satchel charges everywhere. You could use the kamikaze barge strategy and will do most damage than a standard kamikaze barge. If you dont like dying(obviously) then you could hang the bomb over the edge of the barge using a damaged pipe so that you or a friend drops it over an enemy base (this technique requires weeks of training and is hard to master).
Another more easier way is to have 3 people. You will need a sacrifice and 2 people with satchels. This is the exact same way as the tank but the sacrifice is launched by a launch pad on a barge. It is better this way as the guy with the bombs can walk to the enemy pumps or main pipes which will shut down the base entirely(though explosives will easily counter it as well as turrets and miniguns).
OH YES DONT FORGET the laser drill toppler. The laser drill, oh yes, this thing literally eats through blocks of the map and making it disappear into oblivion. You can use a sneaky barge under the map while carrying a group of people with laser drills. With 1 person you can drill the pillar of a base in less than 30 seconds(counting the time it takes to pull the iridium from the ocean). This strategy is too overpowered early game as long as you have 600 iridium and a barge. The pillar gets drilled so quickly that the enemy has barely any time to react and place an anchor. It is really overpowered.
