Era iPhone - Weapon Upgrades

[xAndrewx]

Weapon upgrades are available-

When you buy a weapon, they have no boost stats. You can increase the damage now, by +1

After two weeks of buying an item (or having an old item) you will have no bonus, after two weeks you will loose -1 damage, after 4 weeks -2 damage.
If you upgrade, you will gain +1 damage. It requires minerals to upgrade weapons and also cash. For each upgrade costs an extra $100. (So from -2 to +1, would mean origional price + 100 [-1 damage] + 100 [-2 damage])

What does this mean: release of new weapons gradually!! yaaaay
