Praise God for His blessing, we are able to invest in 5 more used but with higher spec computers which Blackshot can be played on it. Since the boys know that my cc have Blackshot, more has been coming every day. And 5 computers aren't enough so we tried installing graphic card to 4 more computers and it works, Blackshot can be played on them. Now we have 9 computers with Blackshot. Even that, it is still not enough. Praying that God will continue to bless us and we will have the means to add more higher spec computers.
