Alternate Mine Warheads.

[Suicide Junkie]

What you do is:
1) play a game with the mine limits set to 5000
2) mix 500 real mines in amongst 4500 fake ones.
3) let the minesweepers explode

Each little escort sweeper kills 9 fake mines before being killed by a real one.
A minesweeper V is only half as effective as a minesweeper I used to be.
Your enemy needs 1000 sweeper components to prevent damage.
If you can deploy 50 real and 450 fake for the price of 60 real mines, you've gotten an extremely excellent deal.
