ever heard of proximity mines and remote detonate? and rocket launcher/gunner and tanks???
if ur team is smart, it will be hard to overrun u with flame tanks
a scouter (usually sniper or someone outsidet here somewhere) spots tanks or attacks MUST report back to allow ppl to prepare base defenseif they haven;t done it
if u think thats cheap...ever seen a group of Mobius and hot wires team rush the tunnel (clearing the mines of course) and once into the base, ION CANNON BEACONS and C4...way deadly too if u r not careful
remember this..it is a strategy game.. after all it is C&C...do think about ways of countering their moves (hey counter strike ^_^)
