  We consider the on-shell amplitudes in N=(1,1) SYM in D=6 dimensions within
the spinor helicity and on-shell superspace formalism. This leads to an
effective and straightforward technique reducing the calculation to a set of
scalar master integrals. As an example, the simplest four point amplitude is
calculated in one and two loops in the planar limit. All answers are UV and IR
finite and expressed in terms of logs and Polylogs of transcendentality level 2
at one loop, and 4 and 3 at two loops. The all loop asymptotical limit at high
energy is obtained which exhibits the Regge type behaviour. The intercept is
calculated in the planar limit and is equal to alpha(t)=1+\sqrt{g_{YM}^2
N_c|t|/32pi^3}.
