why have this option, it sounds great, maybe you made the mistake of buying that 1 base to many & didnt have it fully protected and its being taken out and you click self destruct and take out some units that would potentially take out your next base
I see no benefit in having self destruct as a option even for money, I have even clicked it by mistake once! the radious would have to be quite large but the damage could reflect on how much has been added to the base as in same rules as the protction/strength of the base so instead of recycle a few things hit self destruct and waste that base and any money you could of recooped to delay your enemy
thats a idea but there could be so many more, its a waste if you have just brought a base and insteantly been attacked and your offence&dfence surrounding is non existent self destruct would be a great aid and live up to the name!
