I think i found a mistake on page 6... if you say the Limiter has to be OVER 60 you would spawn an enemy every 61th Frame.... so it would be slightly more then 2 Seconds (or am I mistaken?)

You are lying... the full game isn´t very good.... it´s AWESOME^^ (not only the campaign/Special OP´s/Conquest Missions... i love the custom maps ^^)
