They swarm. they come in great numbers, while they also have available very elite troops. also, they are very close combat based. They often come in great swarms, charge up on the enemy so fast that the enemy cannot kill enough of them before they engage in close combat. then, the enemy is done for. this is the time to bring the heavier troops into the brawl.
I think it really depends on how many you have or how much damage they do
Maybe Tyranids? I don't know much about the Lizard men so it's basically a half educated guess
Defineitley 40K.
yes.
Depends. Do you like to swarm your enemies with hoards of terrifying monster and then shred your enemy with countless swipes of razor sharp talons and scythes? then maybe tyranids are your kind of Warhammer 40K army. However tough armies like the space marines will chew through your numbers with powerful ranged weapons and mighty close combat weapons like Deamonhammers and Chainswords. So really it all comes down to strategy and luck
Uh, there isn't a T....If you could post an example that would help. IF it's in the stats it stands for Toughness If it's races it's Tyranids
Answer It depends on your preferences: When choosing an army consider its tactics/playing style or just if it looks cool. Do you like hordes of aliens? Then collect tyranids. etc.
