Nothing too surprising about the firebug but that's certainly not a bad thing! I'm eager to see how it will play and the caulk gun certainly got my attention.
A bit more suspicious about the demolitions though... C4 as a full tier weapon? It seems a bit weird,I don't see it as a "weapon" more like a tool . I hope the T1 weapon will do nicely to make him viable. And the RPG-7 as a T4... I'm also disappointed , as it's certainly a powerful weapon , but I bet it will be quite heavy and will need to be reloaded after every shot? I would have prefered the M32...Then again,maybe it's the T3 , but it would be too overpowered I suppose.
Nice looking maps ! Keep up the good work
