On this mode, EVERY single structure, body, propulsion and weapon of Warzone 2100's main campaign will be available to you.
Take a look from 0:25 to 0:40. Each propulsion has three variants.
The first one is the standard variant. The Mk02 variant gives 50% extra body points and weight, making the unit tougher to be destroyed, but slower to move. The Mk03 variant grants 100% extra body points and weight with the same outcome.
Unlike in the main campaign, the propulsion variants as well the Scrambler Turret and the Plasma Launcher are available without the use of cheats.
Due to the availability of all items, you can now annihilate the Scavengers in numerous ways, consequently increasing Fast Play's re-playability. Just use your imagination.
Two examples below.
I'm also considering to increase the starting power from 2500 to 100000. I feel like you guys will likely want to use the more interesting "toys", but quickly run out of power due to their high price.
