Changed

• Warning arrow for boss' dash attack now takes its radius into account (therefore shows full extent of the danger zone).
• Reduced boss speed slightly.
• Leaking Snailshell artifact now kills a percentage of all active aliens instead of just one alien.
• Reduced max HP of green-shelled aliens seen in Wave 8.
• Upgrade prices are now hidden when at max level.

Fixed

• Warning arrow for boss' dash attack now disappears correctly if the boss is killed while using its dash attack.
